could not find function "as.party.Weka_tree"

I'm struggling with an error message that I don't understand. I'm doing some decision trees and everything goes fine, until I try to plot it

plot(as.party.Weka_tree(CostSensitive_Tree))

which gives this error:

Error in h(simpleError(msg, call)) : 
  error in evaluating the argument 'x' in selecting a method for function 'plot': could not find function "as.party.Weka_tree"

I checked multiple times with help.search("as.party.Weka_tree")and the package ( partykit) is installed, what could be the cause of this error?

Thanks!

First, you need to make sure that the package is loaded, i.e., library("partykit"). Second, you should not call the S3 method directly but just say as.party(CostSensitive_Tree). Internally the as.party() generic function then dispatches to the as.party.Weka_tree() method but the latter should not be called directly.
