I'm afraid this is nowhere near enough information for anyone on this list
to provide any sort of meaningful insight. At the very least we need to
know:

  * What operating system are you using?

  * Specifically, for "large data set" questions-- are you running a 32 or
64 bit operating system and how much RAM do you have?
 
  * What version of R are you running?

  * What does your data set look like and where does it come from?

  * How big is the data set?

  * How are you trying to read the data in?

You don't need to provide the complete data set-- just a representational
sample that someone interested in your problem could replicate into
something of the appropriate size. This is very critical as it is very
possible that the problem is arising from feeding R corrupted data rather
than R simply choking because the data set is "too big".

Without this information, the best you can hope for from this mailing list
is silence or a flippant response.
