ctree - party package multivariate response variables
...anatory variables (columns 52 and 53). Rows are my sampling sites.
I wrote:
species<-rs[,2:51]
v1<-rs[,52]
v2<-rs[53]
tree<-ctree(species~v1+v2)
It does not work , but when I use the same formula for the univariate case (i.e.
a single column - e.g. the total number of species in each samplig sites) it
works. I know that ctree can handle multivariate response variables, but I
cannot figure out how to do that.
Someone can help me?
Thank you
