[R] Running out of memory when using lapply

I'm afraid I programmed something totally non-sensical and inefficient,
but I can't figure out how to do it better.
I have a list of ~ 40 000 characters. I want to take each element at a
time, map it to a large data frame with
hit=which(data.frame$column==elementFromList), then compute some
statistic on data.frame[hit,] and return a result that consists of
either 1) a list of integers or 2) a character.
On a small scale, this works and returns something like
 405 406 407 16351
If I try this with the entire 40 000 character list, though, I get the
"Reached total allocation of 1022Mb: see help(memory.size)" error message.
Can someone please give me a hint how to solve this problem correctly?
