R help - Feb 2005 - taking data out of a dataframe

hello,

I have a problem with using the results of a certain function.
This function is the "tree" function. If I use it to produce a tree
say
with the data "iris" from the help page, I can see the
"attributes" of
my result. Now I need to use a column of the attributes of my tree
ir.tr, is there any way or function that permits me to take this column out?
THanks in advance
Nicolas

In general if you are using a package, it helps to identify the package. I
assume it is the tree package.

Is this what you are after (from the example on the ?tree page)
> attr(ir.tr,"ylevels")
[1] "setosa"     "versicolor" "virginica"
