Dear useRs, I have this funny thing going on with me since morning. I am 32 bit window 7 system with 4 GB RAM(2.95 usable). I tried to run a code on it but when I tried to convert dataframe to matrix by using the following code mat<-matrix(as.numeric(unlist(SFI)),nrow=nrow(SFI)) *where SFI is my dataframe. an error came up, "Error: cannot allocate vector of size 237.3 Mb" I tried to increase memory by using memory.limit(2500) but to no effect. Kindly help me out on it as you always do. Thanks, Eliza

So there is no memory left. Clean uo, use a 64-bit OS, ...... Best, Uwe Ligges

The short answer is "get a bigger computer or find a way to do the computation using less memory". Best, Ists
