R assertion tools

[baileyb0t]

warnings and errors in R don't seem to work as consistently as they do in other languages. I've personally used the options() method to raise warnings to errors so that I can inspect specific lines, only for R to keep running with warnings. I know there are finicky cases with different datatypes that can pass through a stopifnot() call, too.

I'd like to do a comparison of different built-in tools like stopifnot() and libraries like assertr to see how they compare in terms of flagging and raising errors within a script

Hi @baileyb0t ! If this is still something you're interested in working on (2 years later) I'd be interested to help! I've used assertr, assertthat and custom functions to identify errors and give user-friendly error messages.

Hi @jessmhoehner! Apologies for being slow to respond, but I think that sounds neat. What's the best way for you to contribute? I'm partial to Rmarkdown/Jupyter-notebook-style demos but open to what makes sense for you / the methods you want to share.
