I can't directly answer your question regarding 'expression', but can you just
replace b, c,d, and e with coef(obj)[1], coef(obj)[2], ... etc. You still can
automate the whole process this way, right?

This is just one single decision tree, not forest. If you're asking what
package I use to construct one single tree, it's 'rpart'.

Without the actual data, it's hard to see what's going on here, but It seems
you have to restructure your data object to a "long" table, then it should be
easy to use 'dotplot' to generate your plots.

Gurmeet,
I think Xin is more interested in the common axes, rather than just one single
xlab or ylab.
Jim's solution is much more fancier than mine :-)

Hi list,
Is there a way in "rpart" to force the variables only used once when doing the
splits?
This is how the question came about. Often time, the tree constructed uses the
same variable (say X1) for the first and second splits, for example. However,
due to practical reason, the researcher
Thomas,
If you're thinking to leverage your R programming skill in learning SAS, you'll
be disappointed, as the two have quite different grammar. The book Erik
mentioned is a good start. After that, just reading the SAS help file, which
is pretty comprehensive, will keep you busy.

Thanks, David!

Hi Prof. Harrell,
Could you please elaborate on why chi-square test is more appropriate in this
case? Thank you very much!

Not sure why you want to do that b/c this can be done with one function call of
"xyplot" in lattice.
Anyway, you can always set axes=F and then replot each axis using 'axis' for
each plot. Make sure before you do that, set your xlim and ylim, so all four
plots have the same xlim and ylim. Lik
In this case, deploy them as a R package is the way to go.

I wonder how to fix that?

Hi Ista,
Thanks for the reply!
You actually misunderstood me. I never objected the "tmp <- latex(x)" method
(in fact, that's what I'm doing now in my .Rnw file). As I stated in my
original post, I'm simply curious about what causes the error window and wanted
to get to the bottom of it.

Don't quite understand your question, but it looks like a more IT issue to me.
I guess you store your R scripts in a central location (e.g. a server) and
everybody call them from their own workstation, right? Or you can always
bundle your R scripts into a package and distribute it around your
