First, load the `{report}` package:

```{r}
library(report)
```

## Getting started with correlations

Let's start by demonstrating some features with simple tests. The function `report_table()` can be used to create a table for many R objects.

```{r}
results <- cor.test(mtcars$mpg, mtcars$wt)

report_table(results)
```

We can also obtain a shorter version by running `summary()` on the output (that we are going to store in a variable called `t` - like table)

```{r}
t <- summary(report_table(results))
t
```

In the example above, running just `t` ran `print(t)` under the hood, which prints the table inside the console. However, one can nicely display that table in markdown documents using `display()`.

```{r}
display(t)
```

We can further customize this table, by adding significance stars, 


```{r, results='asis'}
display(t,
  stars = TRUE,
  title = "Table 1",
  footer = "Correlation in the mtcars (n = 32) dataset.\n*** p < .001"
)
```

## *t*-tests, ...

It works similarly for *t*-tests.

```{r}
results <- t.test(mtcars$mpg ~ mtcars$am)

t <- summary(report_table(results))
t
```

Note that, by default, `report_table()` prettifies the printing: that means that the column names and its content is, underneath, not necessarily what is printed, which can be a bit confusing. For instance, while the confidence interval `CI` appears as one column, it this actually made of three columns! One can access this *raw* table as a dataframe:

```{r}
as.data.frame(t)
```

In fact, the function used to *prettify* the output is called `insight::format_table()` and is accessible to you too, so that you can prettify the output while keeping it as a data frame.

```{r}
insight::format_table(as.data.frame(t), stars = TRUE)
```

Also, you can join the results of multiple tables:

```{r}
results1 <- t.test(mtcars$mpg ~ mtcars$am)
results2 <- t.test(mtcars$wt ~ mtcars$am)
results3 <- t.test(mtcars$qsec ~ mtcars$am)

results <- c(
  report_table(results1),
  report_table(results2),
  report_table(results3)
)
display(results)
```


## ANOVAs



## Linear Models

```{r}
model <- lm(Petal.Length ~ Species * Petal.Width, data = iris)

report_table(model)
```
