respectively.
They have slightly difference because of the two slightly different data I

there any methods to pl
Rpart and Tree are the same for a
same data when using the default value of parameters, no matter what the
structure of data is?
Thanks very much!

Hello useR,
Could you please tell me how to draw the decision boundaries in a scatterplot
of the original data for a LDA or Rpart object.
For example:
> library(rpart)
>fit.rpart <- rpart(as.factor(group.id)~., data=data.frame(Data) )
How can I draw the cutting lines on the orignial Data?
Or
