Hi, Neeraj.

This means that you are out of memory.  See here:


as well as ?Memory, ?memory.limit, and ?memory.size.

I assume this is R-2.10.1, but sessionInfo() output should always be
included in a post to the list, just to be sure.  This is not a
problem specific to the version of R but has to do with lack of memory
available to R itself.

Hope that helps,
