Help with multtest (rawp2adjp)
Hello R experts,
I am trying to analyze this dataset and am stuck on this problem for quite
some time now.
I am using mt.rawp2adjp.
the output that came out was a matrix with two colums since I had asked it
to calculate the adjusted p values using one method.
so it has the two columns as: rawp BH
I combined these using cbind with my actual dataframe.
checked using head all was fine.
thereafter 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

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...

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(26,830,31042,337, lower.tail=F)
>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
have 3121 possible tests according to 3121

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.

hist() basic question
Hi,
This is a very basic question, but I would like to undestand hist(). I
thought that the hist( , freq=FALSE) should provide the relative
frequencies (probabilities), and so they should sum 1, however:
set.seed(2)
ah <- hist(rnorm(100), freq=F)
sum(ah$intensities)
[1] 2
set.seed(2)
bh <- hist(rlnorm(100), freq=F)
sum(bh$intensities)
[1] 0.4999996

Linking to the BH package introduces CRAN warnings
Dear all,
I'm working on a project that links to the BH package
(http://cran.r-project.org/web/packages/BH/index.html).
My packages doesn't call entry points which might terminate R nor
write to stdout/stderr instead of to the console.
However, it seems some of the codes in the BH package
might. At any rate, when I include some boost headers such as

[PATCH 0/40] ocfs2: Detach ocfs2 metadata I/O from struct inode
The following series of patches attempts to detach metadata I/O from
struct inode. They are currently tied together pretty tightly.
Metadata reads happen via the ocfs2_read_blocks() functions, writes via
both jbd2 and ocfs2_write_blocks().
- Each inode has a cache of associated metadata blocks stored on its
ip_metadata_cache member. The ocfs2_read/write_blocks() functions

Crash report: projection pursuit & predict
Folks,
The projection pursuit regression function in the base R seems to crash when the optimization level is set to zero, i.e. the initial ridge terms are accepted without refitting. I encountered this problem in an out-of-sample prediction exercise using predict. But further investigation suggests the issue is with the ppr fit and predict just sppeds up the crash. The other optlevels seem to be

BH correction with p.adjust
Dear List,
I have been trying to use p.adjust() to do BH multiple test correction and have gotten some unexpected results. I thought that the equation for this was:
pBH = p*n/i
where p is the original p value, n is the number of tests and i is the rank of the p value. However when I try and recreate the corrected p from my most significant value it does not match up to the one computed by the

[PATCH 0/6] Quota fixes for 2.6.31-rc4
Hi,
I did some more in-depth testing of OCFS2 quota code, especially with ECC
feature enabled and spotted some problems. First four patches fix them.
I need the fifth patch to be able to mount OCFS2 filesystem with 2.6.31-rc3.
The sixth patch fixes a potential problem when quota syncing interval is
updated while the cluster is running (which is not possible currently).
