no labels when plotting dendrograms
...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.

is then an equivalent of partition.tree for rpart?
...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.

changing the ordering of leaves in a dendrogram
...age 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!

computing misclassification table for tree objects
I have a classification tree that I computed via the tree function
(in the tree package). I'd like to compute a misclassification table
(if that's the right term) on the data used to compute the tree. That
is, I want to compute a table with the different classes (i.e.,levels of the
response factor) on the rows and the columns, and where entry [i,j] is
the number of times the tree

load in 1.4.0 not working for me
I'm having trouble with save and load in R 1.4.0 (on RH 7.2) I originally
noticed this with a large R object, but it happens with a tiny one as well:
> a <- c(1,2,3)
> save(a,file="test.RData")
> a1 <- load("test.RData")
> print(a1)
NULL
The file "test.RData" is created, and it does have something in it. When
I tried saving a

does function predplot still exist?
Venables and Ripley's MASS 3ed mentions a function predplot, used for
plotting results of lda and 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exist somewhere, or has it been replaced by a new and improved version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.
