increasing memory

Hi.  I want to use R with very large files, a couple hundred megabytes,
but R crashes every time that I try.

Reading help files seems to indicate that R ought to manage its memory
itself.  I know I have enough memory since stata handles these files 
perfectly well.  I have a mac running OS 10.3 and am running RAqua 1.8.1.

Is there anything I can do to make it deal with these files successfully?

I guess you mean R gives an error, but does *not* crash (if it crashes, 
it is a bug that needs to be fixed, and you should cross-check with a 
recent version of R).

If it gives an error, either read in the data in a more appropriate way 
(if there is any, but we do not know how you tried to read in the data), 
or "increase memory" as the subject already suggests.

If it actually crashes there is a bug, but I suspect that it stops with an
error message -- please do read the posting guide and tell us exactly what
happens.

            

      
      
      
    

        
That tells you very little: R and stata work in different ways.  How much 
memory do you have?
