As the error says, you're obviously running out of contiguous wired  
memory (RAM).

You didn't tell us anything about the size of the data - and it seems  
to be of considerable size, because it fails on allocating ca. 350MB  
bytes at once. Whether what you do is difficult or not, that I don't  
know, but obviously you don't have enough memory for what you're  
trying to do. Basically that means you should reconsider your  
approach. Once you provide more information you may want to ask  
Bioconductor users about this issue, but it's definitely not a bug in R.

Cheers,
Simon
