Spearman probabilities and SuppDists
cor.test and SuppDists give me different P-values for the same
Spearman's rho. Which is correct, or am I doing something wrong?

dependency help for FC2 rpm
I am having difficulty with dependencies for the R rpm for Fedora Core 2.
In attempting to load R-2.0.0.0.fdr.1.fc2.i386.rpm it fails the

library is located in: /usr/local/lib.
How might I tell R where to find this library? I am new to Linux and

samba-3.0rc1 Can access PDC but not others
Hello,
I am trying to migrate an NT domain from an NT PDC to a samba3.0 PDC
without disrupting users or requiring them to change passwords, etc. The
complication is that there are NT fileservers in the domain already, so
it's important that the users be transferred to the samba machine with
SID's and RID's intact (so they can access these shares with the same
permissions).

[BioC] limma, FDR, and p.adjust
You asked the same question on the Bioconductor mailing list back in August. At that time, you
suggested yourself a solution for how the adjusted p-values should be interpreted. I answered
your query and told you that your interpretation was correct. So I'm not sure what more can be
said, except that you should read the article Wright (1992), which is cited in the help entry for

topTable function from LIMMA
Dear R-Help,
I am using the function "topTable" from the LIMMA package. To estimate
adjusted P-values there are several options (adjust="fdr" , adjust="BH")
as shown below:
topTable(fit, number = 10, adjust = "BH", fit$Name)
I guess any of these options (fdr, BH, etc.) is using a default of
FDR=0.05 which is quite conservative (i.e., very

permutation-based FDR
Hola a todos,
Tengo un pequeño problemilla...
Tengo unas 9000 variables que he contrastado con 1 en concreto con el test

esta corrección, pero te pide que le pongas las variables con las

false discovery rate !
Dear All,
It is not a typical R question (though I use R for this) but I thought someone will help me. For the list of P values, I have calculated FDR using p.adjust() in R (bioconductor). But my FDR values are same for all the P values. When do we get same FDR values? Does the smallest P values should less than 1/N? (where N is the number of P values)
Thanks in advance.
Kind regards,

FDR analyses: minimum number of features
Dear List,
We are planning a genotyping study to be analyzed using false discovery
rates (FDRs) (See Storey and Tibshirani PNAS 2003; 100:9440-5). I am
interested in learning if there is any consensus as to how many
features (ie. how many P values) need to be studied before reasonably
reliable FDRs can be derived. Does anyone know of a citation where
this is discussed?

Redirect standard input and output of R
Dear R-people!
I??m trying to write a C program that write to the standard input of R
and read the standard output.
I can perfectly read the R output, but I??m not able of writing anything
to R.
This program really works with the 'cat?? UNIX command, but it does not
work with R. What I??m doing wrong??? It is possible to do it???
I want to start R once and use it thousands of times...

Partek has Dunn-Sidak Multiple Test Correction. Is this the same/similar to any of R's p.adjust.methods?
The Partek package (www.partek.com) allows only two selections for Multiple
Test Correction: Bonferroni and Dunn-Sidak. Can anyone suggest why Partek
implemented Dunn-Sidak and not the other methods that R has? Is there any
particular advantage to the Dunn-Sidak method?
R knows about these methods (in R 2.1.1):

FDR in p.adjust
Hello,
I've a question about the fdr method in p.adjust: What is the threshold of
the FDR, and is it possible to change this threshold?
As I understand the FDR (please correct) it adjusts the p-values so that for
less than N% (say the cutoff is 25%) of the alternative hypothesis the Null
is in fact true.
thanks a lot for help,
+regards,
