[R] newbie file size question

I've just recently started using R and have a very basic question. Sorry all, I've searched the postings and couldn't find the answer. I'm trying to read a very large ascii file 1,461,363 rows(data points) x 200 columns(time points) for a few hours now and R seems to be 'frozen'. I'm wondering if there are file size limits or if this is just a really large file and it's just going to be very slow. I believe my read.table syntax is correct - I had everything working just fine with a small subject of this data (only 20 rows x 200 columns). My data is stored and processes running on the University's High Performance Computing system (SUN machines) and believe it's using 4 CPUs. Any ideas?  

Thanks for the help,
