Use of htest class for different tests
Hello!
First of all I must appologize if this has been raised previously, but
search provided by Robert King at the University of Newcastle seems to
be down these days. Additionally let me know if such a question should
be sent to R-help.
I did a contribution to function hwe.hardy in package 'gap' during the
weekend. That functions performs Hardy-Weinberg equilibrium test using

Sweave and \input or \include LaTeX commands
Hello!
I was just wondering if Sweave can work with \input or \include
LaTeX commands. So, is it aware of such a possible hierarchy in
documents. I would test that, but I don't have such a report
available at the moment.
I thought of that when I was writting shell script for Sweave
from command line and I have solved that part there.

"Special" characters in URI
Hello!
I am crossposting this to R-help and BioC, since it is relevant to both
groups.
I wrote a wrapper for Entrez search utility (link for this is provided bellow),
which can add some new search functionality to existing code in Bioconductor's
package 'annotate'*.

How to get mode (the most frequent value in distribution)?
Hello!
I have a continous distribution and would like to get mode (the most
frequent value in distribution). I easily found mean, median and other
basic thing but not mode function. Can anyone help?
I know there my might be problems with multiple modes, but still I think
that there should be a mode function in R.
Please send mail to R-help list and me, so I can get response faster.
Thank

I am producing a set of images and I would like them to be sorted by names

F90
Hello!
Has anyone successfully compiled F90 sources in R-package? I found the
same question on r-devel list from 2002 and I wonder if there is any
progress. I heard that g95 and gfortran can be usable.
And one more thing. I have a program written in F90 and lets suppose that
compiler is not a problem. I've read manual 'Writing R Extensions' and
successfully loaded one F77 subroutine

Upgrading R
Hello!
New version of R has came out and I would like to thank to all developers
on this matter. So I should probably upgrade. Fine and no problem. For
windows I just grab the latest precompiled binnaries and install them. Then
I see a report on a bug, which is or will be fixed in pacthed version. So
I need to get binnaries from patched build and install them, right?

Constrain coefs. in linear model to sum to 0
Hello!
I would like to use constrain to sum coeficients of a factor to 0 instead
of classical corner contraint i.e. I would like to fit a model like

effectA_2
effectB_1
effectB_2

where effectA_1 represents deviation of level A_1 from intercept and
sum(effectA_1, effectA_2) = 0 and the same for factor B.
