I have a decision tree I generated using the tree class. When I call
text.tree, if the tree is split on a categorical variable, the text over the
split says, for instance, "variable:afn," if the split occurs on the 1st,
6th, and 14th levels of the variable. Unfortunately, if the tree splits over

Mike,
there are many examples of embedding R, one of them is rJava/JRI and you can
see how to initialize R with custom callbacks at
http://svn.rforge.net/org/trunk/rosuda/JRI/src/Rinit.c
Cheers,

Hello,
I'm new in exploring R-internals,
and also did not explored embedding R into C.
I did some C-extensions for packages so far.
Nevertheless I can give you a hint,
which might be helpful; the example which you linked to,
uses R.dll.
DLL means: Dynamic linked library.

Hi,
is there a reason why `slot<-` should duplicate its argument?
I am under R 2.12.1.
Thank you,
Renaud
For example:
setClass('A', representation(data='matrix'))
a <- new('A')
x <- matrix(1,2,3)
tracemem(x)
slot(a, 'data') <- x
