softwareRisk: Computation of node and path-level risk scores in scientific models

Arnald Puy

The R package softwareRisk leverages the network-like architecture of scientific models together with software quality metrics to identify chains of function calls that are more prone to generating and propagating errors. It operates on tbl_graph objects representing call dependencies between functions (callers and callees) and computes risk scores for individual functions and for paths (sequences of function calls) based on cyclomatic complexity, in-degree and betweenness centrality. The package supports variance-based uncertainty and sensitivity analyses to assess how risk scores change under alternative risk definitions.

Installation

install.packages("softwareRisk")

To install the development version, use devtools:

install.packages("devtools") # if you have not installed devtools package already
devtools::install_github("arnaldpuy/softwareRisk", build_vignettes = TRUE)

Usage

Please see the vignette for a walkthrough of the package utilities.
