R help - May 2010 - Memory issues using R withing Eclipse-StatET

Hi useRs,
I use R within Eclipse via StatET, and it seems to me that some memory
intensive tasks fail due to this environment.

For example: I was trying to find the distance matrix of a matrix with
(10000 rows and 500 columns), and it failed in StatET, whereas it
worked in vanilla R.

I'm using R 2.10.1 on WinXP.

Thanks for any help in this matter.
Regards,
Harsh
