As i described in the original post I ran
> example(ctree)
and the following part yields an error:
if (require("ipred")) {
data("GBSG2", package = "ipred")
GBSG2ct <- ctree(Surv(time, cens) ~ .,data = GBSG2)
plot(GBSG2ct)
treeresponse(GBSG2ct, newdata = GBSG2[1:2,])
}
Error in Summary.Surv(c(1814, 2018, 712, 1807, 772, 448, 2172, 2161, 471, :
Invalid operation on a survival time
