Hello everyone,
I use the following command lines to get important variable from
training dataset.
data.controls <- cforest_unbiased(ntree=500, mtry=3)
data.cforest <- cforest(V1~.,data=rawinput,controls=data.controls)
data.cforest.varimp <- varimp(data.cforest, conditional = TRUE)
I got error: "Error in model.matrix.default(as.formula(f),data =
blocks): term 1 would require 4e+17 columns"
I changed data dimension to 150. The problem still exists. So, I guess
there are other problems. Please give me some help or hints. Thanks!
jinrui,
