# randomForest MDSplot help R [closed]

I am new to R and randomForests so bear with me. I am trying to visualise my randomForest a little better using the MDSplot() function in Random Forest. There are two things i would like to do, and i dont know if they are possible or sensible.

1) Instead of just having colored markers on the MDSplot i want to have my sample names (row names) so i can see where each row falls, to see where each point clusters.

2) When i used my randomForest to predict on new data, i want to overlay them on the MDSplot (i.e. the PCA built from the proximity matrix which i trained my RF on) so that i can see how close the new data points lie next to the orginal clustered groups.

• (1) forestfloor package (2) ggRandomForests - I haven't tried either. But they both take a different approach than it seems that you're planning in interpreting the model. – charles Feb 5 '16 at 0:04
