Use str_sub() in the stringr package:
require(stringr) # install first if necessary
s <- "abcdefghijklmnopqrstuvwxyz"
str_sub(s, c(1,12,17), c(3,15,-1))
#[1] "abc" "lmno" "qrstuvwxyz"
Thanks. That's very close to what I'm looking for, but it seems to
correspond to "cut -c", not to "cut -f". Can it work with delimiters or
only with character counts?
