We need more details.  Have you followed all the hints in ?read.table and
the Data Import/Export manual?  If you have, then probably your data set
is too large for the memory of your version of R, and the simplest
solution is to get more memory.

To be more helpful we would need full details of the dataset and of the 
commands you used and the environment you are using (OS, how much RAM and 
how much virtual memory at least).
