Counting Arguments In R

Kevin Feasel



Neil Saunders shares methods for interrogating argument lists in R:

“Some R functions have an awful lot of arguments”, you think to yourself. “I wonder which has the most?”

It’s not an original thought: the same question as applied to the R base package is an exercise in the Functions chapter of the excellent Advanced R. Much of the information in this post came from there.

There are lots of R packages. We’ll limit ourselves to those packages which ship with R, and which load on startup. Which ones are they?

It’s a fun exercise and helpful for learning a bit more about how to work with arguments when metaprogramming in R.
