For an R tutorial I want to show how easy it is to see the source code of a function by just typing the name in the console / pressing F2 in Rstudio. I'm looking for a function that is

- written in R (not using .Call, .External, .Internal etc)
- simple (not calling UseMethod)
- short
- common (in base/stats/graphics etc)
- useful

I'm currently thinking of rug, but that already has quite some if-else levels. Any nicer ideas?

plot(density(faithful$eruptions))
rug(density(faithful$eruptions))
rug

(Of course I'll in a second step reference to https://github.com/wch/r-source/blob/trunk/src/library/graphics/R/rug.R and e.g. How can I view the source code for a function?)

How about `ncol`? – Weihuang Wong Oct 25 '16 at 15:55
nice idea. Good example to then spiral down towards .Primitive("dim") – Berry Boessenkool Oct 25 '16 at 15:57
This question will be probably be closed. But looking at specific methods for certain generic functions could be useful. For example `head.matrix` is short and easy to understand. – Dason Oct 25 '16 at 16:43
