Issue with using as.numeric with group field in simdat data frame.

[edwardody]

I'm new to github so I hope this is an appropriate issue to raise.

Running the code in lines 129-138 in raincloud_tutorial_r.Rmd produced the following error:

NAs introduced by coercion
Removed 500 rows containing missing values (stat_boxplot).

The resulting figure does not include the boxplot.

The issue appears to be that the contents of simdat$group cannot be converted to numeric class using as.numeric. Instead the character vectors are converted to NA. I changed the contents of simdat$group from "Group1" and "Group2" to "1" and "2" in my own copy of the script and the code now runs.
