Hi,

I have been using some code for multivariate random forests.  The output
from this code is a list object with all the same values as from
randomForest, but the model object is, of course, not of the class
randomForest.  So, I was hoping to modify the code for predict.randomForest
to work for predicting the multivariate model to new data.  This is my
first attempt at modifying code from a library ....and I am afraid I am
already out of my depth.  I was able to access the predict.randomForest
code, and extract the relevant information, but this code it calls a
function regForest that I cannot seem to find/access.

Another blog gave the following instructions for accessing the regForest
function: "Download the source package of randomForest, extract the tar.gz
and look in the src directory. In rf.c you will see the function
classForest (and for regression look at regForest in regrf.c)."

I downloaded the randomForest tar.gz and extracted it using 7 zip, but I do
not get an src directory.  I only get a gz file called
randomForest_4.6-6.tar.gz.   The randomForest library already is installed
in R, so I looked in the main src directory in R, but there isn't any rf.c
or other randomForest related information there.   I am sure I am making
some easy to remedy mistake, but I can't figure it out.

Any assistance would be greatly appreciated.
