Please use the BioC list for questions such as this. It has been  
discussed numerous times there. I am cc: my answer to that list.

This just means you do not have enough memory. Do not fret over the  
specific values, R just bangs out at some kind of assignment  
somewhere in the code.

Well, you still do not have enough ram. Note though that R cannot use  
all of the 4GB due to limitations of the OS. So it will not help to  
add more RAM.

Install an OS which can actually use all your RAM.

You could try reading in smaller subsets of the data, instead of  
everything in one go, although you will probably have problems when  
you normalize (at least if you want to normalize all chips together).  
How many chips are you looking at (and how big are they?)
