Re: [R] interpretation of MDS plot in random forest

here it is an amended (more general) version library(randomForest) set.seed(1) data(iris) iris.rf <- randomForest(Species ~ ., iris, proximity=TRUE, keep.forest=TRUE) x<-MDSplot(iris.rf, iris$Species) #add legend legend("topleft", legend=levels(iris.rf$predicted), fill=brewer.pal(length(levels(

Re: [R] interpretation of MDS plot in random forest

sorry, in fact it was a trivial question! by just peeping into the function I've worked out this simple solution: MDSplot(iris.rf, iris$Species) legend("topleft", legend=levels(iris$Species), fill=brewer.pal(3, "Set1")) thank you > thanks andy > > it's a real honour form me to get a reply by yo

Re: [R] interpretation of MDS plot in random forest

thanks andy it's a real honour form me to get a reply by you; I'm still a bit faraway from a proper grasp of the purpose of the plot... may I ask you for a more technical (trivial) issue? is it possible to add a legend in the MDS plot? my problem is to link the color points in the chart to the fa

Re: [R] interpretation of MDS plot in random forest

Yes, that's part of the intention anyway. One can also use them to do clustering. Best, Andy -Original Message- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Massimo Bressan Sent: Monday, December 02, 2013 6:34 AM To: r-help@r-project.org Subject
