Wilcoxon test on data matrix
Dear everyone,
I am trying to do a Wilcoxon one-sided test on my gene expression data.
These are the data i have in R:
data.matrix (matrix, numeric) containing all gene expression data (42 rows=genes, 42 columns=tumors), no column header or row names
data.cl (vector, numeric) consisting of 42 0's and 1's to indicate class 0 or class 1 for each column in data.matrix
I want to do a

Are post-hoc tests being developed for R?
Hi-
Is anyone working on multiple comparisons of means or post-hoc tests
(ie: Tukey, Bonferroni) for R? I saw in the winter 98' archives of the R
mailing lists that these tests had not been implemented yet, I was just
wondering if I could look foward to having them. ;-)
I also looked through the contributed packages and didn't see anything
that offered such tests.
I guess I could check

substituting own test statistics in a built-in function
Hi All
I would like to compute the raw p-value from permutation tests and I found
mt.sample.rawp() from the package multtest almost similar to what I want to
do. But in the function definition:
mt.sample.rawp(V,classlabel,test="t",side="abs",fixed.seed.sampling="y",B=10000,na=.mt.naNUM,nonpara="n")
I would like to choose my own t-test which is designed

how to convert factors to numbers
Hello, I am relatively new to using R. I am using R version 2.8.0. I have a
program that downloads stock data from Yahoo! Finance and stores it to a
text file on my hard drive. The text file contains the date, opening price,
high price, low price, closing price, volume and adjusted price (i.e.,
adjusted for dividends and splits). I want to read and manipulate the data
in R. However, when I

permutation-based FDR
Hola a todos,
Tengo un pequeño problemilla...
Tengo unas 9000 variables que he contrastado con 1 en concreto con el test
de wilcoxon. He calculado el p-valor, y queria corregirlo con el
permutation-based FDR. He encontrado una funcion con R comp.fdr()que hace
esta corrección, pero te pide que le pongas las variables con las
observaciones y te hace el test (según he entendido). Yo solo quiero

R-beta: Re: Post-hoc tests
Matt,
Here's a Bonferroni-corrected multiple one-sample t-test that I wrote
some years ago. It took a while to get it into R, as na.omit doesn't
seem to handle vectors and I had to write a quick kludge (na.remove).
Another more general point was that I discovered that the help page for
t.test gives the name "parameters" for the degrees of freedom, as in S.
However, the name

Multiple testing corrections on very large vector
Hello all,
I am calculating probabilities of association for terms in the
GeneOntology database. I have ~4e7 probabilities and I would like to correct
for multiple testing. At the moment I have something like the following:
pv is a vector containing my 4e7 probabilities.
To run the multiple testing corrections I do:
mt <- mt.rawp2adjp(pv, proc="BH")

Re: Need help on how to list functions from a loaded package...
To All
How does one get a list of functions from a loaded package so that one can
then get the appropriate help for each of the functions. Currently my
method is
based on a lot of trial-and-error.
Here's an example of what I mean...

Isn't r-announce supposed to be moderated? I posted to r-announce about a
minor update in randomForest and was rejected. I was told that it's meant
for new or significant upgrades in packages, etc.

desperate!
Dear R community
I sent a message out a while ago asking for help with multiple
comparison tests for ANOVA's, but haven't had any response yet.
I'm sending a final desperate plea. If I can't get this done in R I'm
going to have to redo a whole lot of stuff in a commercial package,
which I'm REALLY not keen to do!
My problem is how to implement these tests in R. Below

dynamic lists at C level
Dear R-devel,
I am trying to do something similar to dynamic length lists in R, but
at C level.
In R, that would be rather trivial:
- determine the length of the list
- create the list object
- store the values for each component
- access value components by using "[["
At C level, for a single component where I need to store a vector of
length 5, I do:
int *p_result;
SEXP my_list =

[Bridge] [PATCH v2] net: add ETH_P_802_3_MIN
Add a new constant ETH_P_802_3_MIN, the minimum ethernet type for
an 802.3 frame. Frames with a lower value in the ethernet type field
are Ethernet II.
Also update all the users of this value that David Miller and
I could find to use the new constant.
Also correct a bug in util.c. The comparison with ETH_P_802_3_MIN
should be >= not >.
As suggested by Jesse Gross.
Compile tested only.

FDR for hypergeometric tests
Dear list,
I have performed several tests for the hypergeometric distribution
using phyper() for some gene annotation categories as follows

>phyper(16,387,31042,337, lower.tail=F)

I am only running some selected categories but I would like to correct
this value for multiple testing since I

Re: Need help on how to list functions from a loaded pack age...
You can get help on the whole package by
> help(package="multtest")
which is likely pretty close to what you want. There's the index etc for the
package on the web as well. You can also just look in the package's
installation directory. If it's loaded you can do an ls(2) say if it loaded
in position 2, to get all objects in the package.

nv50: shader generation patches
Hi ! I've been trying to improve NV50 shader generation a bit the last couple of weeks, so here is
what I've produced. I don't know if it's usable for you or just a pile of horrible hacks, but at
least it makes some mesa demos render more correcly, p.e. the teapot (aside from mip-mapping issues
of the floor texture), arbfplight, and I think the gears also didn't appear as they
