[R] large data set issues

[clayton.springer@pharma.novartis.com]

Dear R-help,

I am loading data sets of the size 509 x ~9000 integers. Which is a 10M
file on disk. The .Rdata is 18M. When I try to use rpart I get:

Error: protect(): stack overflow

Naturally, the same thing happens with randomForest too.

What can be done, or is this dataset really too big?

thanks advance,

Clayton
