hi,
I have a question regarding cp values in rpart(). When I use plotcp() I get
a figure with cp values on the x-axsis, but then I use printcp() the cp
values in that list are different from the values in the figure by
plotcp(). Does someone know why?
printcp() gives the minimal cp for which the pruning happens.
plotcp() plots against the geometric mean (see the help pages!)
