apart). I would appreciate suggestions about other comparable books which, if
possible, have examples using R/S code (instead of SAS).
Thanks,

simplifying randomForest(s)

really new. But I haven't been able to find any comments in the literature

Any suggestions/comments?

removing NULL elements from a list

very same list without the NULL components (i.e., I do not want to unlist or
otherwise loose the rest of the list structure). I can do that with a loop,
but how could I do it without a loop?

eval(parse(text vs. get when accessing a function
...alledf(x)
## do more stuff
}
Two questions:
1) Why is the second better?
2) By changing g or h I could use "do.call" instead; why would that be better?
Because I can handle differences in argument lists?
Thanks,
R.

Looking for packages to do Feature Selection and Classification
Hi All,
Sorry if this is a repost (a quick browse didn't give me the answer).
I wonder if there are packages that can do the feature selection and
classification at the same time. For instance, I am using SVM to classify my
samples, but it's easy to get overfitted if using all of the features. Thus,
it is necessary to select "good" features to build an optimum hyperplane
(?).

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,

Can't find nls()
Hi,
I looked for the nls() function and couldn't find it. In the refman.pdf
it's mentioned as part of the nls package which I cannot find and I also
read something about the MASS package, also impossible to find for me.

Anova
Hi,
I have a microarray matrix 3000x70 for example (genes x
experiments). This data has more than 2 classes. I would like
to make some filtering on the genes. For example, I would like
to exclude genes with the same mean expression across all
classes. This is a problem of ANOVA
H0:mu1=mu2=...=muk
H1: at least one is different
First question: Do you think Anova is reasonable for this?

gls with "crossed heteroscedasticity"
...y.formula,
weights = varComb( varIdent(form = ~ 1 | ID), varIdent(form = ~ 1 | ID2)))
This seems to work (and to produce reasonable results) but I am not sure if it
is right, or I am doing something dumb.
Best,

to me that this might be the obvious, unproblematic way to go, but I

What am I missing?

Interaction between R and Perl
Hello!
I'm calling R from Perl with Statistics-R perl module for a microarray
analysis integrated web tool.
I have some questions for a multi-users utilisation:
- Can I change the directory where R is running in order to have a directory
per user? Then no problem of erasing R data of an other user.
- If it's not possible, can I limite the number of users at the same time? I

rpvm/snow packages on a cluster with dual-processor machines
Hi,
does anybody know how to use the dual processors in the machines of a cluster? I am using R with rpvm and snow packages. I usually start pvm daemon and add host machines first, and then run R to start my computing work. But I find that only one processor in each machine is used in this way and the other one always stays idle. Is there any simple way to tell pvm to use the two processors at

(no subject)
Hello,
I'm trying to write code for a repeated measures ANOVA. To put things in
perspective, I'll describe my experiment (briefly). I have a 2X2 factorial
design with pH (5.5, 6.5) and local community (present, absent) as my treatments.
I had plastic enclosures that I sampled across five weeks with the density of
7 species acting as my response variables. I'm analyzing one
