ctree for suvival analysis problem
...448, 2172, 2161, 471, :
Invalid operation on a survival time
and for treeresponse(GBSG2ct, newdata = GBSG2[1:2,]) I get this error:
Error: extends(class(y), "Surv") is not TRUE
(I care more about treeresponse but assume it is related).
Any help would be highly appreciated!
Thanks,
Ofra
