Updating qvalue and xtable
Good Morning Everyone, I was going through my list of FTBFS packages today and I fixed all my R packages but 2: qvalue and xtable. qvalue requires ggplot2 xtable requires: lsmeans, spdep, splm, sphet, plm I am not doing any R anymore these days and in fact spot has been the one maintaining most of my R packages these days (thanks spot!!), so I am not really interested in maintaining more R

qvalue
Dear colleagues, This is not strictly a R question, but I hope it is ok to ask on the list. I fed a vector of p-values from about 20 million anova tests to the package q-value and obtained this output: > qsummary(asso_p.qvalue) Call: qvalue(p = asso_p.vec) pi0: 1 Cumulative number of significant calls: <1e-04 <0.001 <0.01 <0.025 <0.05 <0.1 <1

How to get the tuning parameter lamda in storey's qvalue package
Dear All, In Storey's estimator of the proportion of true nulls, the estimator depends on the tuning parameter lamda. Suppose now that an estimator of this proportion has been obtained by the qvalue package, what is the lamda that corresponds to the estimate? How to get this lamda?

Re: [BioC] limma, FDR, and p.adjust
Mark, there is a fdr website link via Yoav Benjamini's homepage which is: http://www.math.tau.ac.il/%7Eroee/index.htm On it you can download an S-Plus function (under the downloads link) which calculates the false discovery rate threshold alpha level using stepup, stepdown, dependence methods etc. Some changes are required to the plotting code when porting it to R.

limma, FDR, and p.adjust
I am posting this to both R and BioC communities because I believe there is a lot of confusion on this topic in both communities (having searched the mail archives of both) and I am hoping that someone will have information that can be shared with both communities. I have seen countless questions on the BioC list regarding limma (Bioconductor) and its calculation of FDR. Some of them involved

[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 p.adjust(),

Hello all, I'm trying to use the package qvalue. Upon trying to install it I'm running into trouble.

"Optional" package dependency
Hi all, apologies if this has been answered before, I didn't find the answer in the archives. I am putting together a package that I would like to have optional functionality if another package is installed. In normal, non-package code, I would simply write something like if (require(qvalue)) { # use package qvalue } else { # do not use package qvalue } If I do something like that in a

Unicode Support for MS SQL Server
In order to coerce Rails 1.2.x into supporting Unicode values for an attribute in a model, I found I had to do the following: 1) Change the underlying column type from varchar to nvarchar. 2) Prepend any quoted values going into nvarchar columns with a capital-letter-N, e. g. ''unicode'' becomes N''unicode'' In order to accomplish this, I modified

calculating p-values from t-values for a Bonferroni adjustment
I am performing a sequential bonferroni adjustment on the results of an ANCOVA but the equation I have for calculating p-values from the t-values is not working. I can't seem to find it anywhere else. This is the code I have now: 2*(1-pt(t,df)) where t=t-value and df=degrees of freedom from the ANCOVA. Is there an error in the code? maybe another way to find the p-values? Help! -- View this
