Dear R-users,
I'm working with the Rpart package and trying to understand how the
procedure select the best split in the case the method "class" and the
splitting index "Gini" are used. In particular I'd like to have look to the
source code that works out the best split for un unordered predictor.
Does anyone can suggest me which functions in the sources I should consider
?
Any input would be highly appreciated.
Thank you
Paolo
