Re: [R] Plotting rpart trees with long list of class members

Thanks. Very helpful. You can use the information from the splits in the first tree, to define a new grouping variable, which will simplify the plot: suvar <- sort(unique(test_set$list_var)) test_set$var_grp <- as.factor(testtree$csplit[match(test_set$list_var, suvar)]) testtree2 <- rpart ( lis

Re: [R] Plotting rpart trees with long list of class members

Here is some sample code. It generates a class (list_var) that is used in rpart. list_val is the dependant variable. The plot shows all the values of the class, which is a mess and makes the plot unuseable. I'd like to either suppress the list entirely or replace it with something like "Group 1

Re: [R] Plotting rpart trees with long list of class members

If you provide a simple example, with actual data and code so that we can reproduce your issue, it would make it easier for readers of this list to help. Jean MarkBeauchene wrote on 07/06/2012 04:38:32 PM: > I have a class with 732 members, so using rpart.plot is giving me a tiny plot > in

[R] Plotting rpart trees with long list of class members
