does function predplot still exist?
...qda. But even with the library MASS loaded,
R (1.4.1) tells me predplot doesn't exist, and when I search the 1.4.1
documentation for predplot, it finds nothing. Does predplot still
exist somewhere, or has it been replaced by a new and improved version
with a different name? Thanks.

load in 1.4.0 not working for me
...something in it. When
I tried saving a large object, I watched what was happening with xosview,
and there is some serious disk-writing happening. When I tried loading,
there is some serious disk-reading happening. But no object is returned.
Am I missing something obvious here? Thanks.

is then an equivalent of partition.tree for rpart?
...e (since trees
produced by rpart are superclasses of those produced by tree). Is there an equivalent of
partition.tree for objects of class rpart? Actually, what I'd really like is one that
worked for any number of continuous predictors, but let me choose which two to plot. Thanks.

no labels when plotting dendrograms
...ot;)
str(dend1 <- as.dendrogram(hc))
plot(dend1)
dend2 <- cut(dend1, h=70)
plot(dend2$upper)
plot(dend2$lower[[3]])
So... does anyone know how to cut an hclust object and get a
list of hclust objects, or how to plot a dendrogram object with
labels? Thanks.

computing misclassification table for tree objects
....e.,levels of the
response factor) on the rows and the columns, and where entry [i,j] is
the number of times the tree classified an observation of class i as
one of class j.
My guess is that there's a simple way to do this, but I can't figure out
how. Does anybody know? Thanks.

changing the ordering of leaves in a dendrogram
...ven something as simple
as putting the higher average code on the left would help.
I've spent some time looking at the code in rpart, but I'm having a hard
time figuring out what I need to modify. Or maybe someone's already done
something similar? Any help much appreciated!
