Dear all, I am trying to run a random forest on a 4-class dataset with 10 215 variables. Whatever the number of trees (I was thinking of combining the trees), I first got the error on Windows:
Error: cannot allocate vector of size 407562 Kb In addition: Warning messages: 1: Reached total allocation of 511Mb: see help(memory.size) 2: Reached total allocation of 511Mb: see help(memory.size) We did then try on linux on a super calculator with 130 Go of RAM and 68 processors of 1.5Ghz each. We then got the following error: Error: protect(): protection stack overflow Execution halted Is there anything that can be done to run this random forest ? In the ?Startup I did not understand how to increase the stack size...
