[R] getting last 2 charcters of a string, other "text" functions?

[Gabor Grothendieck]

Note that this one can be slightly simplified by using sub instead of gsub
(since you only will have one match anyways) and the $ is not needed
since .* will consume the maximal matching string:

sub(".*(..)", "\\1", mystring)
