PLS regression?
Hi all,
I would like to do some QSAR analysis (quantitative structure activity
relationship). I need to use some Partial Least Squares (PLS) regression,
but I have not seen this option on the R-project. Is it possible to do this
kind of regression on R?
thank you in advance
best regards,

Question about package coin
Anyone know if coin can run a permutation test based on a (user-defined) statistic other than the mean difference? The function independence_test does the permutation t-test via difference in means. I'm wondering if it's possible to use independence_test to run a permutation test for some other statistic than the difference in means. For example, I'd like to run a permutation test

Dear sir,
I am Shibu John from Thrombosis Research Institute India. It is a

Cream Text Editor
I'm interested in easing my way into learning VIM by first using the Cream
text editor, liking the idea that it will work on both my Linux and Windows
computers. I've installed Cream on my Linux machine, but can't figure out
how to make Cream talk to R? Does anybody know? I'm using Ubuntu if it
makes a difference. Thanks.

Durbin test for Incomplete block
Hi R-users,
Does anyone know of a package that contains a function to conduct
Durbin's test and it's extension for incomplete block designs, as
described in Rayner and Best 2001 "A contingency Table Approach to
Nonparametric Testing"?

A naive question about permutation tests in the coin package
Dear R helpers,
I am trying to understand how to use the independence_test function in
the coin package. I think I suffer from a misunderstanding about what
the package does. Either that or I do not understand how to use it
properly. Specifically, I cannot understand if I can test independence
of arbitrary statistics.
Take the following example:
set.seed(10)
d <- data.frame(y = c(rnorm(10,

Extraction from an output
Hello,
Would you tell my how to extract a result from a test - it's justified because I need to run this test many times. Here is an example from authors' test:
> library("coin")
> lungtumor <- data.frame(dose = rep(c(0, 1, 2), c(40, 50, 48)), tumor = c(rep(c(0, 1), c(38, 2)), rep(c(0, 1), c(43, 7)), rep(c(0, 1), c(33, 15))))

wine reading iso images as cdrom ?
Hello all,
I keep iso images of my most commonly used cdroms on the harddisk so I
don't have to find them. Can I set up a cdrom drive in my wine config that
points to the isos, and have wine think its a cdrom drive ?
Thanks,
Andy

Jonckheere-Terpstra test using coin package?
Is it possible to implement the Jonckheere-Terpstra test for ordered
alternatives using the coin package: Conditional Inference Procedures
in a Permutation Test Framework?
I found jonckheere.test{clinfun}, but it uses a normal approximation
when ties are present in the data. To make this concrete, I've
include
a small dataset. Thanks. --Dale

Labeling matrix data
Hello all -
I am sorry if this simple question is addressed in somewhere else. But, I couldn't find it. It's been for about a week using R. . .
My problem is:
Reading matrix data with "scan" does not seem to allow me to incorporate matrix labels (columns, and rows).
If I use read.table, I can import the lables. But, the problem is, I don't know how I make this data as

Permutation Test on Interactions {coin}
Dear List,
I'm interested in performing a permutation test on the interaction between
a binary treatment indicator and a covariate (either continuous or
categorical). I'm interested in the p-value of the interaction effect from
a permutation test, and I'm using the coin package for that purpose.
As I haven't seen any examples like this in the package documentation (or

Extracting Element from S4 objects
Are there internal methods available for R2.6 (I'm using the mac os x gui)
for extracting (or subsetting) S4 objects?
Using the independence_test() function implemented in the COIN package, I
can't seem to select out p-values upon completion of each iteration of a
loop.
Sorry if my search was incomplete beforehand.
