I'll teach an "avanced" R course for my doctoral school in a month now.
I want to dedicate at least one session (out of 9 or 10) to base R.
Obviously, a part will be about the different accessors.
Yet, I also want to present some useful R base functions. Note that I don't want to talk about functions like
transform because we will use dplyr instead for this kind of operations.
Yet, I remember the first time I discovered the
match function, I found it very useful and now use it very often. There are some other functions like this one that deserve to be known, for example
A complete list of R base functions is available there.
So, here my question is: do you know some other R base functions that are super useful and should therefore be mentioned in my course to come?
