Data Exchange with StatDataML for MATLAB
The e1071-group is developping a data exchange package based on XML,
called StatDataML.
Both read and write functionality is available for R/S and
MATLAB/Octave.
Now here is a snapshot from the "StatDataML for MATLAB/Octave"-package.
It should work fine, but the installation procedure needs some
improvement yet.
I think the following will nevertheless make it run:

Documentation of ``Extract'' re. drop argument (PR#4297)
Problem:
?Extract
does not clearly state that the `drop' argument can only be used in
subscripting, but not in subassigning.
Example:
x <- t(1:10)
x
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
[1,] 1 2 3 4 5 6 7 8 9 10
x[,1:5,drop=F] <- 10:14
Error: incorrect number of subscripts
but
x[,1:5] <- 10:14
x
[,1] [,2] [,3] [,4]

SVM module: scaling data applied to new test set without using SVM again
Hello!
We are new in using R. We use the SVM module from the library ''e1071''
for training.
Problem formulation:
a classification has been performed using SVM module (linear kernel).
Later, a new data set (test set) comparable to the training data shall be
scaled in the same way as the training set (using the same scaling
parameter set, but without using the SVM again

svm regression in R
Hallo,
I have a question concerning SVM regression in R. I intend to use SVMs for feature selection (and knowledge discovery). For this purpose I will need to extract the weights that are associated with my features. I understand from a previous thread on SVM classification, that predictive models can be derived from SVs, coefficiants and rhos, but it is unclear for me how to transfer this

svm
Hello list,
I want to apply svm from library e1071, and I want to supply class weights.
I do not really understand the help entry (and there is no example)
class.weights: a named vector of weights for the different classes,
used for asymetric class sizes. Not all factor levels have to
be supplied (default weight: 1). All components have to be
named.

segfault using svm from e1071 (PR#1178)
This could be a bug in the e1071 svm code, but maybe not -- I guess I'll
send it here anyway. It's reproducible.

PXELINUX and PowerSave Mode ...
We have a lot of diskless Linux clients which are booting via PXELINUX
or ETHERBOOT. The problem is that they are on for 24 hours and APM
PowerSave mode works for ETHERBOOT only. But in the future we want to
use PXELINUX only, which seems to have no features for APM or ACPI
PowerSave included. Would it be possible to integrate such features in
PXELINUX or is there a way to boot a special image

compiling R under hpux
Dear R user,
I'm wondering if anyone was succesful in compiling R under hpux 10.20
I couldn't compile verion 1.2.1 or 1.3.
I asked this question two weeks ago, but nobody replyed. Looks that not
many people are using hpux machines.

Feature Request: "matrix[1:10,1:10, block=F] <- 1:10"
Hi Guys,
I've again been surprised when something like
> m <- matrix("", nrow=3,ncol=3)
> index_i <- c(2,1,3)
> index_j <- c(1,3,2)
> vals <- c("a","b","c")
> m[ index_i, index_j ] <- vals
> m
gives block-wise application of the assignment:
[,1] [,2] [,3]
[1,] "b" "b" "b"

I'm unable to download R from any of the CRAN mirrors. A ny sugge (PR#7823)
Friedrich,
Thank you for your prompt response. Unfortunately, none of the CRAN mirrors
seem to be working for me. I'm not really sure what's going on since I was
able to download R about a year ago, but I recently got a new computer and
needed to download it again. I'll see if my support staff here at the
National Institutes of Health have any suggestions.
Thanks again,

How to concatenate a variable and assign value
for(i in c(1,50,100,250)){
Then I want to create a variable called:
graph++i <- histogram...
}
Any ideas?
With hist it is easy to create multiple graphs on a page but with the trellis
histogram, I am finding it a bit more awkward. It seems that I have to use
print(graph1, split=c(1,1,1,2), more=T) to achieve the desired result. Does
anyone have code they are willing to share which
