Error when I try to build / plot a tree using rpart()
Hi,
I am using the rpart package to build a classification tree. I did
manage to build a tree with data on a previous project. However, when
attampting to build a tree on a project I am working on, I seem to be
getting the error shown below:
> nhg3.rp <- rpart(profitresp ~., nhg3, method="class")
> plot(nhg3.rp, branch=0.4, uniform=T); text(nhg3.rp, digits=3)
Error in yval[, 1] : incorrect number of dimensions
The distribution of my binary dependent variable is:
> table(nhg$profitresp)
0 1
3703 4360
I am using 10...
