Hi,
I am doing feature selection for my dataset. The following is
the extreme case where only one feature is left. But I got
the error below. So my question is that do I have to use
more than one features?
sample.subset
udomain.edu hpclass
1 -1.0 not
2 -1.0 not
3 -0.2 not
4 1.0 hp
5 1.0 hp
> randomForest(hpclass ~., data=sample.subset, importance=TRUE);
Error in if (n == 0) stop("data (x) has 0 rows") :
argument is of length zero
