tree error
Hi- I'm trying to run a classification tree, and have received an error
I'm unfamiliar with. Following is the R code, and the first 10 lines of
my matrix. Any help would be appreciated.
> kuv.tree <- read.table("kuv3_mantelmatrix.txt",header=T,sep="\t")
> library(tree)
> attach(kuv.tree)
> ktree <- tree(Species ~ Drig + dwellln, data=kuv.tree)
Error in arg == choices : comparison (1) is possible only for vector types
