[R] gbm package: plotting a single tree

[ElenaC]

Hello,

I'm not sure if Im posting this on the right place, my apologies if not. 

I'm using the package gbm to generate boosted trees models, and was
wondering if there is a simple way of getting a graphical output for a
single tree of the sequence. I know the function "pretty.gbm.tree" can be
used to print information for a single tree, but I've been unable to find a
way to visualize this on a plot, similar to those that can be obtained by
plot.rpart (in the rpart package). 

Is there a method for doing these plots within the gbm package? If not, can
the info for a single tree be converted into a different tree object with a
method for plotting? (i.e., is it possible to convert the data into an
object of class 'rpart'?)

Any help would be greatly appreciated!

Thanks,
Elena
