Thanks for your reply Bert. But the question on how to plot MDS on predicted data I guess belong to here!

Now my question is how can I plot MDS on predicted data? here is my code: > > > > spl=sample.split(df$PatientType,SplitRatio = 0.7) > Train=subset(df,spl==TRUE) > Test=subset(df,spl==FALSE) > SecondTree=randomForest(PatientType~ cookie + curtains + get + mother + > overflowing + sink +thats + window + stool + heres + drying + chair + okay > +outside + standing + tipping + windows + blowing + breeze +counter + finger > + onto + open + reaching + didnt + spilled +action + quiet + summer + mouth + > puddle + good + wind +whos + sort,data = > Train,nodesize=25,ntree=200,proximity=TRUE) > PredictForest=predict(SecondTree,newdata =Test) > Is MDS plot a way to find out if the classification are easy to be separated? This seems to be largely a statistics question and, if so, is OT here (this list is about R programming) I suggest you post this on stats.stackexchange.com instead.
