Running out of memory when using lapply
Hi all!
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.
res=lapply(listof40000,myfunction,dataframeToSearchIn)
On a small scale, this works and returns something like
str(res)
[[1]]
[1] "UNIQUE"
[[2]]
[1]...
