Hi, I got the following comment from the reviewer of a paper (describing an algorithm implemented in R) that I submitted to BMC Bioinformatics: "Finally, which useful for exploratory work and some prototyping, neither R nor S-Plus are appropriate environments for deploying user applications that would receive much use." I can certainly respond by pointing out that CRAN contains

I don't know if this is the correct forum to ask the following question; however, when I search the aroma.affymetrix discussion group, it suggested that I should posted the question to r-help. Here it goes. I followed the instructions on aroma.affymetrix trying to install the packages; following are the steps: > install.packages(c("R.oo", "R.utils"),

Hi the list Is there a way to know how many times an R package (on CRAN) has been download ? Christophe

During installation of a package, Makevars/Makefile in src/ is processed. I've always considered the purpose of this for compiling native code. Is that it's solely purpose, or is it alright to use it also for non-code compilation purposes, e.g. building inst/ subdirectories on the fly? If not, are there other means to create non-static inst/ subdirectories during installation? The

Dear all, I want to apply a weighted median on a huge dataset, and I remember a function from the package R.basic that could do this using an internal sorting algorithm qsort. This speeded things up quite a bit. Alas, I can't find that package anywhere anymore. There is a weighted.median function in the package limma too, but I didn't use that before. Anybody who knows what happened to

Hi, Is there a way to turn off the automatic inclusion of "./" at the beginning of a path specified in an \SweaveInput{} instruction? I'd like to create some reusable "template modules" of Sweave code and put them in a standard directory like /Resources/Affymetrix Then the corresponding file that uses one of these would include a command like

Hi, I recently provoked some discussion over on the BioConductor developer list about testing and R CMD check. In brief, the salient points that arose from the discussion are: [1] Because of the need for a nightly build of BioConductor, the tests (in the ./tests directory) of a package that run routinely as part of "R CMD check" must complete in five minutes. [2] Nontrivial

Hi, I got an interesting programming challenge: How do you inspect an object which is assigned via delayedAssign() and that throws an error as soon as it is "touched" (=the value is evaluated)? Is it possible? MINIMAL EXAMPLE: $ R --vanilla > delayedAssign("foo", stop("Hey!")) (If you find this minimal example silly/obvious, please skip down to the real

Is there any package that allow you to perform "MA plot" like graph for Toray microarray data? Unlike Affymetrix CEL file which contain 2 values (R and G), Torray raw data only contain 1 value. MA-plot is Affymetrix specific which usually available for in (limma) package. P. Dubois [[alternative HTML version deleted]]

Hi, I'm putting together an R package. In explaining how it works (in the Rd files), I want to refer to another package. The other package is not used anywhere in the actual code nor in the examples. So, there is no reason to include the other package in the Depends, Suggests, or Imports lines of the DESCRIPTION file. People will be able to use my package without actually installing

Hello, I've got a DESCRIPTION file with a the first line: Package: Repitools But, when I run R CMD INSTALL Repitools I get: * installing *source* package Repitools ... ** R ** data ** inst ** preparing package for lazy loading Warning in FUN(X[[1L]], ...) : Created a package name, "2011-04-20 09:05:40", when none found ** help *** installing help indices ** building package

Hi List, I'm trying to install aroma.affymetrix, which depend on many packages, affyio is one of them. The task is done on 32-bit Linux without problem. The same task was done on Solaris 9 with R-2.5.1 without problem. Following is the error message when installation affyio. I did try to put a file stdint.h I got from the web in the path, but got more error messages. Jun root@biostatsun1

Hi, I have two data set of normalized Affymetrix CEL files, wild type vs Control type.(each set have further three replicates). > wild.fish AffyBatch object size of arrays=712x712 features (10 kb) cdf=Zebrafish (15617 affyids) number of samples=3 number of genes=15617 annotation=zebrafish notes= > Dicer.fish AffyBatch object size of arrays=712x712 features (10 kb) cdf=Zebrafish (15617

Dear all, We have developed our own Affymetrix chip (Custom Express Array, PM-only with two species). I want to analyse the data with the limma package, but for that I need to built my own CDF package, probe package and built the filters to analyse one specie or another. I'm using the makeProbePackage available in the AnnotationDbi (for a R-2.13.0) but I got the following error message:

Hi, I have a question concerning the analysis of some affymetrix chips. I downloaded some of the data from GEO GSE11324 (see below). In doing so I'm stuck after I identified the probesets with significant changes. I have problems in assigning probeset specific gene names as well as getting the genomic coordinates. Furthermore I have no clue how to deal with the fact, that most genes have

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

I have a very basic question about limma. Assume I have experiments from 3 or more RNA sources in a reference design. It is easy to define individual contrasts but I want to specify a contrast matrix that tests for significant differences among ALL the different RNA sources (i.e. the analogous thing to a simple One-Way ANOVA). How can I do that? Thanks! Max --

Hello, I wonder if it is unwise to name a bundle the same as one of its packages. For instance, I now have a huge package called 'aroma' that I basically want to split up in several smaller packages, say 'aroma.core', 'aroma.io', 'aroma.explore', 'aroma.trial', 'aroma.deprecated' etc, which simplifies maintenance but also the overview. For

Hi, I'm trying to remove/delete a directory usingR. I've tried the following with no success: % Rterm --vanilla > getwd() [1] "C:/Documents and Settings/hb/braju.com.R/aroma.affymetrix/test" > dir.create("foo") > file.info("foo") size isdir mode mtime ctime atime foo 0 TRUE 777 2007-02-28 14:52:10

Hi, sessionInfo() has been proven really useful, but you still often have to ask for additional information in order to help troubleshooting. For instance, for troubleshooting the aroma.affymetrix, it is very helpful to know what the current working directory is, for other packages certain system environment variables might be useful and so on. One solution could be to provide support for hook
