[R] break up a string into strings with a fixed length

[Gabor Grothendieck]

That part wasn't specified so we can't say what the required behavior
is in that case; however, if a non-multiple of 3 were possible and if
the short string is to be emitted at the end then we can just add to
the regular expression:

> library(gsubfn)
> s <- paste(letters, collapse = "")

> strapply(s, "...|..$|.$", c)[[1]]
[1] "abc" "def" "ghi" "jkl" "mno" "pqr" "stu" "vwx" "yz"
