Helmut Kudrnovsky,
This issue was discussed on this list recently: Search for messages
with Subject: "Fwd: MDS problems" at and after 26 March. Brief answer to
your question is: no, you cannot run isoMDS in MASS if you have zero or
negative dissimilarities. You should remove identical cases. Afte
Well I must say that I am still struggling to understand exactly how fdim
works, and what form the first argument is to take. Presumably the function
produces something like 1-slope for a log log plot as a fractal dimension.
I guess it is really the makeline() function I don't understand from the
Hi,
I am having trouble installing R-1.8.1 on my Fedora 1 machine. R is
already installed in /usr/local on our network, but I wish to be able to
work on my own copy. So I installed it locally using:
./configure --prefix=/scratch/akhan/R-1.8.1
make
make install
The installation looks fine accor
Thanks. I'll update the survey package. Sudaan does the standard errors on quantiles
using Taylor series. If I can hunt down the formula it uses, could you add that to
svyquantile?

Gideon,
You might look into Caswell, H. 2001. Matrix population models 2nd
edition. Sinauer Associates.
Caswell's book covers a majority of matrix population modeling, including
some good introductory information and has general matrix manipulation as
an appendix. I think most of the work i

Hello
I am getting this

I don't know anything about matrix population models, but Golub & Van Loan's
`Matrix Computations' is a standard reference for numerical computations
with matrices. There's also David Harville's fairly recent book, `Matrix

It does, if you don't use source(). Have your R code in one buffer, and
the R session running, and (from the code buffer), type C-c C-l.

Hi Patrick,
It's very simple using a browser() line in your function somewhere you
know your code's OK, then run line by line.
The problem is that sometimes you have code of a few hundred lines, to
which you have added a strange little line that craps out because of
some silly mistake that wo
I am looking for a manual(s) or any kind of documentation, at the introductory level,

I don't think so, but traceback(), debug() and options(error = recover)
are your friends.
Also, you might want to check
Hello,
Is there a way to get complex sample variances in the survey package on summary
statistics other than means? If not, can they be added to a future version? It would

columns percent, etc).
Thanks.

That's the advantage of having an R interface to RF: you can do such
automation rather easily. E.g.,
twoStageRF <- function(x, y, nVar=round(0.1*ncol(x)), ...) {
imp <- randomForest(x, y, importance=TRUE, ...)$importance[,3]
cutoff <- sort(imp, decreasing=TRUE)[nVar]
randomForest(x[, imp >=

It was an HTML approach that Gabor suggested,using R2HTML, and that worked
well, but I will try xtable as well.
As always with R, there is a solution if you know where to look.

character in variable names. See below
