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 is there any built in functions that can read the rpart object 'fit.rpart' to do that?

Thanks very much in advance!
