a problem in random forest
Hi, there:
I spent some time on this but I think I really cannot figure it out, maybe I
missed something here:
my data looks like this:
> dim(trn3)
[1] 7361 209
> dim(val3)
[1] 7427 209
> mg.rf2<-randomForest(x=trn3[,1:208], y=trn3[,209], data=trn3, xtest=val3[,
1:208], ytest=val3[,209], importance=T)
my test data has 7427 observations but after prediction,
> dim(mg.rf2$votes)
[1] 7361 2
which has the same length as my training...

maxit = 200)
