Thanks a lot! Unfortunately, the R package I have to sue for my research was only released on 32 bit R on 32 bit MS Windows and only closed source I normally use 64 bit R on 64 bit Linux :) I tried to use the bigmemory in cran with 32 bit windows, but I had some serious problems.

Corrado, Package bigmemory has undergone a major re-engineering and will be available soon (available now in Beta version upon request). The version currently on CRAN is probably of limited use unless you're in Linux. bigmemory may be useful to you for data management, at the very least, where

looks like you've run out of memory mate, because that sure is a big matrix, you'd probably need 64 bit OS/CPU/R and loads of RAM. see thread: http://www.nabble.com/Error-in-matrix:--too-many-elements-specified-td20457910.html I know there are some packages on cran which help with large datasets

Dear friends, I have to use a very large matrix. Something of the sort of matrix(8,8,n) where n is something numeric of the sort 0.xx I have not found a way of doing it. I keep getting the error Error in matrix(nrow = 8, ncol = 8, 0.2) : too many elements specified Any
