Problem with party and ordered factors
...ornik and Achim Zeileis described in the documentation
party: A Laboratory for Recursive Part(y)titioning
There i got the same problem. I execute the following code:
> data("mammoexp", package = "party")
> mtree <- ctree(ME ~ ., data = mammoexp, scores = list(ME = 1:3, SYMPT =
1:4, DECT = 1:3))
> plot(mtree)
Beside getting one waring everthing's ok. But when i excute
summary(predict(mtree)) the result is:
Never Within a Year Over a Year
412 0 0
So now i'm stuck. Am i doing anything wrong? I'm using R 2.4.1 and all
packages...

Extract node names from BinaryTree in package party
Hi there,
I need to extract the variable names from all nodes (except the
terminal nodes) from a ctree object, e.g.
library(party)
mammoct <- ctree(ME ~ ., data = mammoexp)
plot(mammoct)
how can I extract the varnames from node 1 (SYMPT) and node 3 (PB)
from the fitted object "mammoct"?
Many Thanks, Sven
