Re: [R] FUNCTION ctree

[Achim Zeileis]

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.

If you do

So, you should run
library(partykit)
before running your function call

If partykit is not installed, you need to install it.

Re: [R] FUNCTION ctree

[Sarah Goslee]

Probably load the package that ctree() comes from, possibly party.

library(party)

The code you're looking at should tell you.

Re: [R] function ctree in package party

[Mark Difford]

Hi Maxl18,

 error in mo...@fit(data,...) : object var3 not found
 What should I do? 

Make sure that var3 exists/is available

##
str(datalist$var3) ## is it here?
ls(pattern=var3)   ## is it here?

Regards, Mark.

 Hi,
 I have a problem with the function ctree in the package party.
 
 When I launch ctree with weights=NULL it works.
 ctree(function~var1+var2, data=datalist, weights=NULL,
 controls=ctree_control(mincriterion=0.95, maxdepth=4,

 But when I try
 ctree(function~var1+var2, data=datalist, weights=var3,
 controls=ctree_control(mincriterion=0.95, maxdepth=4,

 there`s an error message

 What should I do? Thanks
