definitive list of changes. This NEWS file will only update major
releases going forward.
rattle 5.3.6 20200501 Graham.Williams@togaware.com

class; varImp log handling.
rattle 5.3.1 20191123 Graham.Williams@togaware.com
* Convert datasets to be tibbles, moving towards tidyverse
compliant. Require tibble package. Also require bitops as needed
when loading a tibble as an RDataset into Rattle.
rattle 5.3.0 20191123 Graham.Williams@togaware.com
* Cleanup and prepare for CRAN release.
rattle 5.2.8 20191016 Graham.Williams@togaware.com
* Remove dependencies on archived packages RGtk2Extras and playwith.
* Bug fix View Data button to just call R's View() rather than a
glade data view or RGtk2Extras data viewer.
* Update weatherAUS dataset with most recent weather observations
now with 166,310 data points.
rattle 5.2.7 20190407 Graham.Williams@togaware.com
* Bug fix - the export PMML file dialog stopped working - perhaps a
RGtk2 update. It was using glade. Instead create the dialog
directly in code. Reported by Julian Ochoa.
rattle 5.2.6 20190331 Graham.Williams@togaware.com
* Bug fix - rattle was incorrectly specifying load instead of open
in a GTK file chooser which did not work on an RGtk2
update. Reported by Dave Arnold and Eric Mattys.
rattle 5.2.5 2018-09-26 17:23:00 Graham.Williams@togaware.com

Dubassarsky.
rattle 5.2.0 2018-08-12 15:17:12 Graham.Williams@togaware.com
* Remove dependency on RGtk2 and check it dynamically. Rattle has
more functionality than just the GUI yet we force installation of
RGtk2 which is problematic on some platforms.
* Return the datasets to rattle package. Has caused too much
confusion as a separate package.
rattle 5.1.6 2018-08-12 15:17:12 Graham.Williams@togaware.com
* Bug fix for new rpart.plot with roundint= handled automatically.

hierarchical clustering. Results in errors for the weather
dataset. Reported by Tony Nolan.
rattle 5.1.3 2017-10-29 21:25:08 Graham.Williams@togaware.com
* Bug fix: xgboost evaluate to score file failing. Needs target in
the precit command to succeed! Actually needs a fix to
predict.xb.formula but include a work arond for now. Reported by
Dwight Barry.
rattle 5.1.1 2017-09-08 16:08:03 Graham.Williams@togaware.com
* Update and bug fix to riskchart for risk AUC as provided by
Cameron Chisholm.
rattle 5.1.0 2017-09-04 08:20:34 Graham.Williams@togaware.com

rattle 5.0.19 2017-07-10 15:14:34 Graham.Williams@togaware.com
* Debug the xgboost interface - limited to binary classifcation
tasks for now. Key is that the R code is exported and can be used
as a template for extended modelling.
rattle 5.0.18 2017-06-27 06:54:48 Graham.Williams@togaware.com
* Tune Boost interface.
rattle 5.0.17 2017-06-24 10:58:15 Graham.Williams@togaware.com
* Move the dataset from the rattle package to a separate rattle.data
package in line with CRAN guidelines to have a separate package
for slower changing datasets of considerable size. This will also
allow the option to provide further datasets for rattle as part of
that package.
* Use weather.csv as the sample for both R and Microsoft R as
weatherAUS.csv is too large to include in a CRAN package.
* Ensure strings are treated as categoricals on loading the data
with Microsoft R so as to conform to read.csv() and to be
consistent with the non-Microsoft R version of Rattle.
rattle 5.0.16 2017-06-17 08:18:26 Graham.Williams@togaware.com
* Update the weather dataset from the Australian Bureau of
Meteorology and add sample weatherAUS.xdf to the package to
be loaded as the default example when Microsoft R is
detected. XDF is a file system based data format used by
Microsoft R to handle datasets of *any* size rather than
being limited by available computer RAM.
rattle 5.0.15 2017-06-17 07:48:30 Graham.Williams@togaware.com
* Merge RevoScaleR (Microsoft R) support for NeuralNetworks and
KMeans from Microsoft India Data Group team.

* Bug fix call to errorMatrix() where counts= is not count=.
* Bug fix to evaluate where respcmd for random forest has
disappeared when incorporating MRS updates.
rattle 5.0.11 2017-05-26 17:43:01 Graham.Williams@togaware.com
* RGtk2 version 2.20.33 released and caused some issues with
Rattle. Heuristic test of libglade/GtkBuilder began failing
and retval no longer used for obtaining returned values.
rattle 5.0.10 2017-04-30 13:57:16 Graham.Williams@togaware.com
* Review predict.hclust() to use cutree() by default and
predict.kmeans() for a Euclidean distance approach as an
option. Bug report by Hamed Mamani.
rattle 5.0.9 2017-04-14 13:17:33 Graham.Williams@togaware.com
* Introduce a checksum for R datasets (data.frames) so that we
can identify when a user has changed the R dataset outside of
Rattle, and have the new version loaded.
rattle 5.0.8 Graham.Williams@togaware.com
* Incorporate updates for ggratpR(). Close to functional and so
it is nearly ready for release.
rattle 5.0.7 2017-03-05 18:13:22 Graham.Williams@togaware.com

rattle (2.6.26) unstable; urgency=low
* Replace .path.package with path.package as requested by Ripley. The
hidden version will disappear soon and the new version has been
available since 2.13.0.
* Update boost help to note that it is available only for binary
classification.
* Default stemming for textmining of a corpus is no active if the
Snowball package is available.
* For Advanced Graphics introduce a dendrogram plot using ggplot2.
* Various text mining improvements. Bug fix in checking if data needs
reloading. Support checking if corpus needs reloading. Add extra
cursor and status bar messages. For corpus, set default folder to be
getwd(). Check for mismatch between number of docs in corpus and the
number of targets in .targets.csv. For the Corpus file dialog, do not
offer folder creation.
* Remove macosx special rattle.ui. The ubuntu specific text no longer
appears in the saved ui file.
* Internally: Move rattleGUI to crv from crs. The crs is saved as the
state, and this was confusing the GUI on a project restore. Had to
ensure we restored rattleGUI with the current rattleGUI - this fixes
loadProject bug. Also, in Load project, filter on .RData not .Rdata.
* Add newdata= to call to predict, in line with the standard approach by
party (reference Torston). Remove the OOB= for predict for
cforest. With a new dataset OOB makes no sense. It was in there
because newdata= was not being used and positionally having issues.
* Update fancy rpart plot to reduce colour intensity for printing and a
nicer tree structure. Add all class probs to fancy tree.
* Define paste0 if it is not defined. It was introduced in 2.15.0 but is
too early to assume the world is with us.
* Replace siatclust with weightedKmeans.
* Bug fix in OOB plot when impute is off - need to omit missing values.
Update message regarding random forest and na.omit() removing all
rows, noting the option to use na.roughfix().
* Fix bug identified by Brian Feeny 121209 - score a RF test dataset
without a target variable tries to add one in all NA but fails if it
is the last variable.
* Experimentally add Deducer's data.viewer to View data. Ensure we ask
user if when using Plot Builder it is okay to create a dataset in
their work space. Hopefully keeps us in line, if not strictly in
copmliance, with CRAN policy.
* Remove SVG support - RSvgDevice is no longer available.
-- Graham Williams <Graham.Williams@togaware.com> Sat, 16 Mar 2013 13:27:05 +1100
rattle (2.6.25) unstable; urgency=low
* Review all of the code and remove two instances of using copyrighted
code without attribution. One was a copy or print.rpart, where rattle
added a translation wrapper to the text message. Another was code
copied from the Internet from David Hand - use the Hmeasure package
now. Note in drawTreeNode() reference to the original author and lack
of copyright. Note author in Authors@R. ggcorplot is now available
from Deducer. Remove it from Rattle. Replace Hand measure with
HMeasure from hmeasure. Add Mark Vere Culp as aux author. Remove
commented out code. Remove lss and cranSearch - not really part of
Rattle.
* Update to new style Authors@R.
-- Graham Williams <Graham.Williams@togaware.com> Sat, 23 Jan 2013 13:12:43 +1100
rattle (2.6.24) unstable; urgency=low
* Bug fix for box plot using ggplot2.
* Finish the implementation of riskchart using ggplot2 to mimic the old
version of risk charts.
* Remove copied code from print.rpart, known as rattle.print.rpart, and
originally used without proper credit to Brian Ripley, but no longer
required. Use his original versoin from rpart itself, though lose the
translations.
* Migrate to a cleaner structure for managing the source package locally
at togaware.
* Bug fix fancy rpart plot to handle regression as suggested by Yana
Kane-Esrig.
* For arules, add option to specify minimum length.
* Update to new version of RGtk2Extras' dfedit, without a pretty_print
option. Also able to assign result into crs$dataset now.
* Remove two instances of global variable assignments. Temporarily
remove PlotBuilder and scoring of manually entered datasets.
-- Graham Williams <Graham.Williams@togaware.com> Tue, 11 Dec 2012 06:45:50 +1100
rattle (2.6.21) unstable; urgency=low

-- Graham Williams <Graham.Williams@togaware.com> Mon, 10 Sep 2012 19:27:42 +1000
rattle (2.6.20) unstable; urgency=low
* Because of use of globalVariables Rattle now depends on R >=
2.15.1. However, check this conditionally to retain backward
compatibility for now. Reported by Uwe Ligges.
* For show arules, eval in global environment else it does not show the
rules. Reported by Tania Churchill.
-- Graham Williams <Graham.Williams@togaware.com> Mon, 23 Jul 2012 02:27:18 +1000
rattle (2.6.19) unstable; urgency=low
* Depend on weightedKmeans rather than siatclust.

definitive resource, though not freely available.
-- Graham Williams <Graham.Williams@togaware.com> Sat, 24 Dec 2011 15:35:21 +1100
rattle (2.6.15) unstable; urgency=low
* Bug fix for Mac OS/X on 2.14.0 with a call to set.cursor failing
because the textviews do not yet exist. Problem is that the
addFromFile for the GUI is generating a Warning that seems to now stop
the file being loaded. Removing the particular XML elemnts causing the
warning (one ubuntu_local and 4 GtkTreeSelections) "fixes" the
problem.
-- Graham Williams <Graham.Williams@togaware.com> Sat, 03 Dec 2011 22:49:18 +1100

rattle (2.6.7) unstable; urgency=low
* Add support for the entropy weighted k-means subspace clustering
algorithm from the ewkm package.
* Ensure rattle can load with only the base package installed (so
install.packages is prefixed with utils:::).

* Deal with UTF-8 encoding of Japanese filenames in data and evaluate,
using iconv.
* Be sure to include http:// in web links, though on MS/Windows still
not working: Could Not Show Link... No application is registered as
handling this file
* On loading a dataset, convert any character variables to be
factors. Rattle does not handle character variables, so the
translation seems appropriate.
* Association rules status bar was refering to decision
trees. Fixed. (Pointed out by Xiaobo Gu)
* Fix an introduced bug in handling of categorics in numeric transforms.
* Fix a bug where imputation for a categoric with class "ordered" and
"factor" was treating it as a numeric (because "ordered" is not
"factor").
* Some Help menu items under Test were not loading the required package
and thus were not displaying the help.

rattle (2.6.3) unstable; urgency=low
* weather.arff Date field should have 'date' data type.
* The rug plot of histograms is no longer coloured. For large datasets,
there is much overplotting and so it can in fact be quite misleading.
* Box plots now use varwidth=TRUE to indicate the distribution of the
target variable.

* Ensure connection is closed on pmmltoc export from Rattle.
* questionDialog needs to not use RGtk2 if RGtk2 is not installed!
* Emphasise that Rattle is free in loading the rattle package.
* exportKmeansTab does not require the file argument.

rattle (2.6.1) unstable; urgency=low
* When exporting a regression model, be sure to use proper slash (i.e.,
not the Windows slosh) for log tab record of the command.
* Add rattle.ui to the google code repository.
* Remove as many literals as possible from the Log tab - so that
crs$dataset[crs$sample, c(2:10,14,16:20)] becomes
crs$dataset[crs$sample, c(crs$input, crs$target)], for
example. Similarly for the set.seed and other data storing variables.
* Other Log tab cleanup.
* Fix bug that caused failure on reading an .xls data file.
* rattle.info() now returns the list of packages that need updating.
* In exporting a model as C code, if we are Japanese on Windows then
note that the encoding is shift-jis rather than utf-8 for some reason.
* Improve infrastructure for the generation of C code from PMML.

rattle (2.6.0) unstable; urgency=low
* Keep track of project names and use as default name to save a project
to. Suggested by David Cochrane.
* Add strip.white to the default for reading CSV files. Suggested by
Robert Muenchen.
* Bug fix on resetEvaluateTab - Data row was being reset to sensitive
because model was being toggled.
* Disconnect Rattle versions from google code revision numbers since the
revision numbers change each change to the Wiki.
* Indicator Variables will Ignore the first of the new indicator
variables. Suggested by Robert Muenchen.
* Include the Target name in listing of a decision tree as a rule set.
* On adding to the log when saving a plot make sure carioDevice is
loaded and the file name path separators are appropriate. Reported by
Shane Butler 11 Dec 2010.
* Ensure filename string is UTF-8 when exporting a file, to handle
Japanese filenames.
* For nnet, choose a seed so weather generates a non-trivial model.
* Refer to remapping as recoding in line with commonly used terminology.
* Default back to showing text on icon for buttons. Seems okay in the
new version of Gtk.

rattle (2.5.47) unstable; urgency=low
* Add a useGtkBuilder argument to rattle(). If NULL, then heuristically
determine, otherwise go with the specified choice, if possible.
* Remove RGtk2, colorspace, and pmml as dependencies. Now dynamically
check and offer to install. This also helps reduce chance of the
XML/RGtk2 zlib1.dll bug, and also ensure RGtk2 loads before XML to
avoid that bug.
-- Graham Williams <Graham.Williams@togaware.com> Mon, 15 Nov 2010 21:50:15 +1100
rattle (2.5.46) unstable; urgency=low

* Check for GtkBuilder handling of the 'requires' tag, and if not
handled the don't use GtkBuilder.
* Bump pmml version through 1.2.25 to 1.2.26.
* Change default nolan groups for a singularity to 50 rather than 99.
* PMML bug fix when glm and using weights.
* Move all variable initialisation from .onLoad to .onAttach. This will
ensure .RData saved (and therefore old) versions of the variables will
not overwrite the proper versions in a newer release of Rattle.
-- Graham Williams <Graham.Williams@togaware.com> Sat, 09 Oct 2010 08:16:15 +1100
rattle (2.5.44) unstable; urgency=low
* Add an include.libpath to rattle.info() to provide information about

* Check for failed startup of rattle GUI using GtkBuider (because the
Gtk library installed does not recognise 'requires' and suggest a
workaround).
* Condiionally turn toolbar Text (in addition to just Icons) on.
* For loading spreadsheets, make sure RODBC is available and loaded.
* Ensure 'ordered categoric' are treated as categoric for Explore,
Distribution.

rattle (2.5.42) unstable; urgency=low
* Update rattle.info() to recursively identify all dependencies, report
their version number and any updates available from CRAN and generate
command to update packages that have updates available. See
?rattle.info for the options.
* Fix bug causing R Dataset option of the Evaluate window to always
revert to the first named dataset.
* Fix bug in transforms where weights were not being handled in
refreshing of the Data tab.
* Fix a bug in box plots when trying to label outliers when there aren't
any.

rattle (2.5.40) unstable; urgency=low
* Conditionalise useGtkBuilder:
if windows and R before 2.12.0 then libglade
if unix and R 2.12.0 then libglade for now (RGtk2 update needed?)
all else use GtkBuilder
-- Graham Williams <Graham.Williams@togaware.com> Sun, 22 Aug 2010 12:02:00 +1000
rattle (2.5.39) unstable; urgency=low
* Conditionally use either libglade2 or GtkBuilder for the
GUI. libglade2 (a separate library to the Gtk+ library) is deprecated
and as of R 2.12.0 won't be supported on MS/Windows binary builds. The
default is now GtkBuilder (built into the Gtk+ library), and support
for libglade2 within Rattle is deprecated. RGtk2 (2.12.18) still has
issues in its support of GtkBuilder and is being actively worked on,
but Rattle is currently working around these.

* Migrate from RGtk2DfEdit to its replacement, RGtk2Extras.
* Revert cairoDevice to being a Suggests rater than Depends.
* Remove redundant CITATION from root of package, as the real one is in
inst.
-- Graham Williams <Graham.Williams@togaware.com> Sat, 31 Jul 2010 14:34:50 +1000
rattle (2.5.36) unstable; urgency=low
* Add Bill Venables' searchCRAN example code.
* Improve error message when we find duplicate variable names in a
loaded file, which might result when there is no header line.
* Add help item for Projects.
* On Evaluate with supplied file, use the hdr specified on the Data tab.
-- Graham Williams <Graham.Williams@togaware.com> Mon, 12 Jul 2010 06:43:06 +1000
rattle (2.5.35) unstable; urgency=low
* Add utility lss function to list object sizes.
* Add options text entry for SVM to easily allow other options.
* Better formatting of the Log tab.
* Use a set.seed for SVM to ensure same model each time.
* Add option to random forest to impute missing values rather than
simply ignoring the observations.
* On Evalaute with supplied file, use the sep specified on the Data tab,
thus allowing TXT files.
* On loading a new dataset for evaluation be sure to add in any missing
columns, and unify the levels.
* Improve binning documentation.
* Make RGtk2, cairoDevice, colorspace all dependencies so we can get
rattle started and then rattle will prompt to install other packages
that are mssing when it needs them.

rattle (2.5.34) unstable; urgency=low
* When a package is missing, there is now the option to install it right
then, and it continues as normal after it gets installed.
* Change Suggests to Depends so all used pacakges get loaded on loading
rattle, in an attempt to make it easier to install Rattle. Then the
r-cran-rattle package on Debian/Ubuntu will have all required
dependencies and a normal install.packages will get all dependencies
also, rather than having to use dependencies=c('Depends',
'Suggests'). Penalty is it takes 20 seconds to do 'library(rattle)' on
a server and 90 seconds on a netbook - so revert back to not doing
this.
* Ensure the new train/validate/test scneario is saved across projects.
-- Graham Williams <Graham.Williams@togaware.com> Wed, 09 Jun 2010 07:04:08 +1000
rattle (2.5.33) unstable; urgency=low
* Bug fix rf.cmd.
* Improve scoring functionality: The dataset can have NA's for target,
and these can now get scored by rf on Evaluate tab. Loading a CSV file
to be scored no longer needs to have the target column included
(previously it needed to be there and have non-NA values). Thanks to
Chris Snijders.
-- Graham Williams <Graham.Williams@togaware.com> Mon, 31 May 2010 06:22:54 +1000
rattle (2.5.32) unstable; urgency=low
* Remove dependency on car - not actually being used at the moment.
* For random forest, allow sample size text entry as a single integer or
a list, as per randomForest.
* Use na.omit with cforest, as is done with randomForest.
* For randomForest turn subsampling with replacement off since it is
more likely to produce biased importance measures, as explained in by
the cforest papers.
* Fix bug with multiple "contact support" lines in error popups.
* When showing the randomForest importance values, sort on the accuracy
measure rather than the Gini measure, since the Gini is biased in
favour of categoric variables with many categories.
* ada boost seed should be 42, like all other seeds.
* Tidy up some ada output.
* Bug fix - save project for rf failing (looking for rf_sampsize_entry).
* Remove text from toolbar by default.
* Change order of Forest/Boost buttons on Model tab.
* Add tooltips for all toolbar buttons.
-- Graham Williams <Graham.Williams@togaware.com> Fri, 28 May 2010 15:47:15 +1000
rattle (2.5.31) stable; urgency=low
* Add rattle.info() to list information for debugging purposes.
* Bump pmml to 1.2.22
* Fixes from wenching.lin@zementis.com: Extension in Header should be
first element. Coefficients in regression models should not be NA (as
will be for singularities), but replace with, and so no impact of
change.
* Ensure Survival defaults are reset appropriately.

* On MS/Windows with Japanese, read.csv needs encoding option set with
file rather than with read.csv (for UTF-8) but seems okay under other
scenarios.
* On MS/Windows with Japanese (UTF-8) the encoding of the variables
selected for transforming needs to be UTF-8 for much of the process,
but "unknown" when using Rtxt and sprintf (when substituting the
variable names) to ensure resulting message is correctly matched for
encodings.

rattle (2.5.29) stable; urgency=low
* Add the translation file.
* Fix an Encoding/sprintf issue for Japanese on MS/Windows.
* Allow crv$NOTEBOOK.MODEL.NAME to be overridden by other packages

rattle (2.5.27) unstable; urgency=low
* Further translation fixes. In particular, use Encoding(...getText())
<- "UTF-8" to ensure strings from the GUI ate UTF-8, and not unknown.
* Ensure training dataset rather than sample dataset nomenclature is now
used.
* Ensure execute button can only be clicked once while it is processing.
* Survival plot buttons need to be made sensitive as appropriate.
* For Japanese on MS/Windows do not use monospace font since this ends
up vertically cenbtering periods and commas (and all other
characters). Need a fixed width font that does not do this, but for
now we put up with variable width font.
* Revert to using only English for all hidden tab labels.
* Improved identification of current plot number.
* Bug fix multiple vars selected for asnumeric and ascategoric
transforms.

rattle (2.5.25) unstable; urgency=low
* Start using the RGtk2DfEdit for the View and Edit buttons of the Data
tab, and the Enter/Score option of the Evaluate tab. RGtk2DfEdit
provides a spreadhseet like interface to the data. Various data
editing options are available. Also press = to run an arbitrary R
command on selected data (e.g. select two columns of data and issue
the plot command).
* Add further markup of text for translations.
* Support specification of the character used for decimal points (to
suit some European usage).
* Fix bug in exporting XML - replace & with &
* Survival plots - split survival chart plot from residuals plots, and
plot all residuals.
* Fix logic behind what is greyed out in the Test tab.

rattle (2.5.24) stable; urgency=low
* Revamp the help text, and put into the Rtxt translation framework.
* Fix the height of the data name widget (the library option was growing
the width for some reason).
* For Evaluate, add Full and Enter as dataset options. Enter will pop up
an editor with the final row from the dataset, allowing you to add
rows or modify the supplied row. We supply the row so that we have an
example to work from. Full uses the whole original dataset.

* Catch "arules" error in converting data to transactions when baskets
contain repeated items.
* When data tab is executed, and so crs$rpart is reset to NULL, always
remove the Draw/Rules button from the Tree option of the Predictive
tab.
* Add code to fix translations that are not being loaded when using
RGtk2 on MS/Windows. All is okay on GNU/Linux, but RGtk2 seems not to
get the right locale for loaded Glade file. The fix is to traverse the
GUI and change all labels, on starting up Rattle. RGtk2 authors tried
to fix but it remains an issue.
* Ensure rpart is reset on resetting rattle.
* Rework handling of tab pages because a Japanese translation on
MS/Windows is having issues with the following call (nd=notebook)
nb$getTabLabelText(nb$getNthPage(nb$getCurrentPage())) returning what
looks like Shift-JIS encoding of the string rather than UTF-8, and
hence not string matching the expected tab label.
* Fix spelling errors on help menu and ensure help for all topics is
covered.
* For nnet, use MaxNWts=10000 (default is 1000) to allow larger nets by
default, and capture the error message when this is exceeded and
better explain what to do.
* Ensure we don't export an empty dataset when choosing export on the
data tab.
* Capture arules error message when there are repeated items in one
basket, and explain this more clearly.
* For rpart use information as the default split rather than Gini - makes
little if any difference.
* Allow showHelpPlus to have an extra/alternative question that is
displayed.
* All random seeds should be 42.
* Reset kmeans tab on loading a project.
* Add dozen more weather stations to the weatherAUS dataset.
* Improve the logic for the display of the Report radio buttons on the
Evaluate tab.
* Spelling correction to a number of tooltips.
