I have a 1360x92735 csv dataset and I have to reduce dimensionality using FSelector package for R (information.gain()), but it requests a lot of ram.
My question is, can I use the ff package in combination with FSelector? If yes, how?
p.s. I have 8GB of ram and 8GB of swap on linux.
Thanks.
[EDIT]
I've try to use ff and FSelector package with iris dataset. It seems to work well, but now I've a problem with ff.
My csv dataset is 1303x92735 and when I try to use an ff object to convert a dataframe with as.ffdf(), or to directly load dataset with read.csv.ffdf(), R crash with "write error".
Here someone has same problem, but I don't understand if reachs a solution or not.
Thanks.
