[R] FW: Large datasets in R

Well, SPSS used to claim that all its algorithms dealt with only one case at
a time and therefore that it could handle very large files. I suppose a
large correlation matrix could cause it problems.

I have a related question. How differently do other statistical
softwares handle large data?

The original post claims that 350 MB is fine on Stata. Some one
suggested S-Plus. I have heard people say that SAS can handle large
data sets. Why can others do it and R seem to have a problem? Don't
these softwares load the data onto RAM.
