R help - Mar 2009 - function ctree in package party

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,
teststat="quad",testtype="Bonferroni"))

But when I try
ctree(function~var1+var2, data=datalist, weights=var3,
controls=ctree_control(mincriterion=0.95, maxdepth=4,
teststat="quad",testtype="Bonferroni"))
there`s an error message
error in model at fit(data,...) : object "var3" not found

What should I do? Thanks

Hi Maxl18,

Make sure that "var3" exists/is available

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

Regards, Mark.
