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", "Group 2", etc. list_var <- rep(NA,2000) list_val <- rep(NA,2000) for (i in 1:1000) { list_var[i] <- paste("A",i%/%25,sep='') list_val[i] <- runif(1,0,1) } test_set <- data.frame(list_var, list_val ) testtree <- rpart ( list_val ~ list_var, data = test_set ) rpart.plot(testtree, type=3) -- View this message in context: http://r.789695.n4.nabble.com/Plotting-rpart-trees-with-long-list-of-class-members-tp4635671p4635915.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
