I'm building a RF 50 trees at a time due to memory limitations (I have roughly
.5 million observations and around 20 variables). I thought I could combine
some or all of my forests later and look at global importance.
If I have say 2 forests : tree1 and tree2, they have similar Gini and Raw
My apologies, subject corrected.

I've had no success using what I think is the correct code to change the
default size of the x, y and z labels in a persp graph (i.e. cex.lab). Is
there a particular specification to accomplish this?
Many thanks,

When using the plot.randomForest method, 3 error series (by number of trees)
are plotted. I suspect they are associated with the 3 default values of mtry
that are used, for example, in the tuneRF method but I'm not sure. Could
someone confirm?
Also, is it possible to force different values of
Hi everyone,
I suspect this is an easy task however I've not been able to accomplish it.
I'd like to create an mtext title which has certain words bold, the rest not
bold. So far I've been able to create one which is all bold, one which is all
not bold and one which has bold and not bold

I was trying to create a multi-color silhouette plot (each cluster a different
color) from clusters created by trimkmeans. This works straighforwardly on an
object created from pam however my colors are interwoven when I try the same
approach on clusters from trimkmeans. I also tried sorting
I don't seem to be able to label the x, y or z axis when creating a 3d chart
using rgl.surface. I'd like to have them parallel to the axis line and move
with the graph when rotated. Can this be done?
Many thanks,

Has anyone created a 2 variable partial dependence plot based on a
randomForest object? Or would anyone have a suggestion as to how to do this?
Many thanks,

Hi Everyone,
I posted a similar, albiet more specific, question a while back and didnt get
a response so I thought I'd try once more with a more general framing.
Basically I'm wondering if anyone has any code, examples/illustrations,
documentation (besides the basic R docs on mda/fda)
Greetings everyone,
I was wondering if anyone had experience in using fda (flexible discriminant
analysis) in the mda package. Specifically, I can run the model but I cant
locate/produce much of anything beyond the predicted values and confusion
matrix. I've been searching for more examples or
