Dear all, I am using Rstudio. What to do when you get this message? Error in plot(ctree(Surv(hours, state) ~ soil + volatile, data = data)) : could not find function "ctree" Thank you, Xavier
Probably load the package that ctree() comes from, possibly party. library(party) The code you're looking at should tell you.

If you do ??ctree and the package partykit is installed, you will see that this function is defined in this package. So, you should run library(partykit) before running your function call If partykit is not installed, you need to install it.> On Mar 10, 2016, at 15:58, CHIRIBOGA Xavier <xavier.chiriboga at unine.ch> wrote: > > Dear all, > > > I am using Rstudio.

Thanks to Erich and Sarah for the clarifications. For those wondering whether ctree() from "party" or from "partykit" should be used: the latter is the newer and improved implementation.
