Full_Name: David L. Van Brunt Version: 1.8-1.9 beta OS: OS X 10.3 Submission from: (NULL) (68.74.58.109) As posted on R-Help (after which another user replicated the problem): --------------- This is the conclusion from a prior thread ([R] " cannot allocate vector of length 1072693248") which ended with no other answer but that there must be a problem in the OS X version of R, or in

When you have fairly large data, _do not use the formula interface_, as a couple of copies of the data would be made. Try simply: Myforest.rf <- randomForest(Mydata[, -46], Mydata[,46], ntrees=100, mtry=7) [Note that you don't need to set proximity (not proximities) or importance to FALSE, as that's the default already.] You might also want to use

This is the conclusion from a prior thread ([R] " cannot allocate vector of length 1072693248") which ended with no other answer but that there must be a problem in the OS X version of R, or in the compile of the source on OS X. I??ve posted code and data here: http://www.well-wired.com/reflibrary/uploads/1084503247.zip If you setwd() into the directory that is made, then ??source()??
