R help - Sep 2002 - large data set issues

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

You could try redefining R_PPSSIZE in Defn.h and recompiling, to get a
larger pointer protection stack.
