Hi Xiaojing, That's a big table!
You might try 'write' (you'll have to work harder to get your data into an appropriate format). You might also try the R-2.7 release candidate, which I think is available here http://r.research.att.com/ for the mac. There was a change in R-2.7 that will make writing large tables without row names more efficient; this might well be where you are running in to problems.
