Dear All, maybe this is something obvious, I seem to be incapable of understanding how S4 works. So, in package 'A' I defined a "summary" method for my class: setMethod("summary", signature(object="ListHyperGResult"), function(object, pvalue=pvalueCutoff(object), categorySize=NULL) { "whatever" })

A post on the Bioconductor mailing list https://stat.ethz.ch/pipermail/bioconductor/2009-May/027700.html suggests that install.packages now references .Rprofile (?), whereas in R-2-8 it did not. Is this intentional? The example is, in .Rprofile library(utils) install.packages("Biobase", repos="http://bioconductor.org/packages/2.4/bioc") then

Dear All, since years I am struggling with Surv objects in data.frames. The following seems to have to do with it. See below the modified example from the help page of survSplit. The original works, as expected. If, however, a Surv object is added to the data.frame, each record gets doubled. Is there some solution other than avoiding Surv objects in data.frames? Thanks, Heinz

I have developed a problem with the postscript output of plot on Windows. My code still works properly with R 2.3 but, with R 2.4, the white text on red background does not show up. It does, however, show up when output is sent to the screen. Below is my code and sessionInfo. R version 2.4.0 Under development (unstable) (2006-08-29 r39012) i386-pc-mingw32 locale: LC_COLLATE=English_United

Hi, I wanted to install Rgraphviz. From the R GUI, I downloaded the package but when I tried to load it I got the following error message: "This application has failed to start because libcdt-4.dll was not found. Re-installing the application may fix this problem." The R commands and errors are: > utils:::menuInstallPkgs() trying URL

Hi everyone, I just installed R 2.10 using the Windows binary. At some point in the past using the Windows binary installation, the default behavior of ?functionname changed from plain text to a nice html interface. Now with R 2.10, the default behavior has changed back to the plain text help. I assume this has some thing to do with these changes listed for R 2.10, but I don't quite

I have produced a series of graphs with the png command, however when I have finally printed these out the black text appears to have a colour shadow with blue or red on either side of the letter. I tried increasing my res to 1200 and this improved it somewhat, but the text is still not sharp and occassionally these "shadows" will still print. I initially thought this was an issue with

Hello list, I'm having troubles setting up a basic calss hierarchy with S4. Here is a simplified schema of what I'd like to do: - Two classes: A and B that extends A - Ensure that the slots added by B are consistent with the slots of A - Let A initialize itself (I'm not supposed to know the internal cooking of A) - By default set the slots of B based on the slots that A initialized

Hi, I have an RData file containing a GeneSetCollection object (Bioconductor), http://www.cs.mu.oz.au/~gabraham/c2.RData. I think it uses lazy loading because packages are only loaded when I access the object (see below) in the R console. When I try the same with Rscript, it segfaults. This happens on 2.9.0 both on Linux and Mac: Rscript -e 'load("c2.RData"); c2[1]' ***

I have recently upgraded to Ubuntu Gutsy and, for the first time, am using a 64-bit installation. After failing miserably to install R from source, not a problem for me in the past with a 32-bit install, I went the route of using the Debian Etch build. This went smoothly, but I am unable to update my numerous R and BioConductor packages, getting non-zero exit status errors on each package. Is
