Dear R-developers, the following may seem a weird question for R-devel – I try anyway, because it does seem to be related to usage of R and R's way of interacting with the hardware. When running R (2.4.0) on my new dual core Windows XP system (Intel Core 2 Duo E6600, Mainboard ASUS P5B, BeQuiet Power Unit), I observe various types of sounds (not related to fans) when running at full

Dear R experts, I have defined a class "myclass" and would like the slots to be extractable not only by "@" but also by "$". I now try to write a method for "$" that simply executes the request object at slotname, whenever someone calls object$slotname for any object of class "myclass". I don't manage to find out how I can provide this

Dear expeRts, I am trying to wrap up a package "utilities" (for my internal use). After adding a function datNAtreat that uses mapply, R CMD check gives WARNINGs for "S3 generic/method consistency", "checking replacement functions" and?"checking foreign function calls", all of which are accompanied by the following error message: Error in .try_quietly

Dear developeRs, I appreciate that boxplot now labels the axes with variable names per default. However, with argument "horizontal=TRUE" (which I always use), the default axis labels are mixed up, as can e.g. be seen with require(boot) boxplot(time ~ poison, poisons, horizontal=TRUE) The correct labels would be obtained by boxplot(time ~ poison, poisons, horizontal=TRUE,

Full_Name: Ulrike Groemping Version: 2.9.0 (and older) OS: Windows Submission from: (NULL) (84.190.173.190) When using an older version of R, packages are not found although they are available for newer versions of R and do work when installed with the old version. For example, installing DoE.base on R 2.8.1 installs version 0.2, while CRAN is at version 0.4-1 currently. It would be nice if the

Dear helpeRs, on my new machine - Windows 7 64Bit, R 2.15-2, I can no longer source files for which the path contains the o-Umlaut (?). As a historical burden, my username is Gr?mping and contains that Umlaut (I wouldn't have chosen it now, but decided to keep it for easy transfer). I have had the difficulty that I couldn't use the R CMD tools on files with Umlauts in the path (and

Dear developeRs, I encounter the following problem: in the current version of my package FrF2, certain calls to a functioni do not work when package combinat is loaded, because function combn from combinat masks the function from utils that my package uses. I tried to solve this issue by importing function combn into the namespace of FrF2; I don't need to export it, I just want to use it

Dear R-helpers, I have a question regarding LU-decomposition with function lu in package Matrix. The following simple example confuses me: Why is as.matrix(elu$U) not an upper triangular matrix? u3 <- matrix(c(1,1,1,1,1,1,-1,1,0,0,0,0,0,-1,1,0,0,0,-1,0,1,0,0,0,0,0,-1,1,0,0),5,6,byrow=T) elu <- expand(lu(Matrix(u3,sparse=F))) as.matrix(elu$U) I only have very limited experience with the

Dear DevelopeRs, I've been struggling with the new regulations regarding modifications to the search path, regarding my Rcmdr plugin package RcmdrPlugin.DoE. John Fox made Rcmdr comply with the new policy by removing the environment RcmdrEnv from the search path. For the time being, he developed an option that allows users to put the environment from Rcmdr (RcmdrEnv) on the search path,

Dear R-helpers, I am puzzled by the following observation: On my home dual core Windows desktop computer, I am used to running two R sessions in parallel. These do very well in using the full CPU of the computer (half each) and don't seem to slow each other down. Today I have started some large computation effort in one of our university labs, and I intended to go for two R sessions per

Dear helpeRs, on my Windows 7 laptop, I have problems getting R CMD check to work. I believe it did work completely before, but I am not sure. Yesterday it almost worked, except for the tests: These were aborted because of a complaint that the temporary directory wasn't available. I played with windows environment variables for the temporary directory, but that didn't solve it.

Dear all, I am working on a function formula.design that should automatically generate reasonable lm formulae for a number of different designs. All works well as long as all variables used are columns of the design data frame. For one function, I would like to incorporate a dummy variable for center points that is not a column of the design. Without this function, it would work like this (at

Dear developeRs, with R 2.4.1 (and also 2.4.0), the function str() fails on objects of class relimplmbooteval, if there are unused slots, which is very often the case. I am not sure whether this is a bug in str() or a correct behavior of str() that unmasks some sloppiness in my usage of S4 classes (that I am not aware of)? Reproducible example (package relaimpo needed): The program

Dear all, I just noticed that the 0.9 update for FrF2 did not work out for Mac OS due to an error in an example that ran without error on all other platforms. I do not find any reason for this. In the past, umlauts or tab characters have sometimes been an issue, but I didn't find any of these. The function definition is FrF2(nruns = NULL, nfactors = NULL, factor.names = if

Dear R-developers, I'm experiencing a problem with having an example run under R 2.6.1 RC (downloaded and installed today, r43513), which does not occur on R 2.6.0: The new version of package relaimpo does list package survey under "Depends", and an example directly (i.e. not only from within a function of relaimpo) uses function svydesign from package survey. Package survey is

Dear developeRs, I just discovered the function plot.design in package graphics that acts as a method for class design - the second time I come across a class design outside my own packages. (The first time was in package conf.design, where Bill Venables encouraged me to ignore it because he does not really use it.) Where can I find out more about the nature of the class design for which

Dear UseRs, I just learnt that the number of columns of a data frame is not always what I thought it to be, and I wonder where I should have learnt about this. Consider the following example: dat <- data.frame(X1=1:10, X2=LETTERS[1:10]) ncol(dat) ## evaluates to 2 (of course) dat$X1poly <- poly(dat$X1,3) dat ## five columns displayed ncol(dat) ##

Dear DevelopeRs, the issue I am stuck with (I am on Windows, R-2.11): My Miktex (version 2.8) does not work with R CMD check, although Miktex on its own can pdflatex the tex-file in the Rcheck directory. (This issue has been going on for a while, and now, after having updated to R-2.11, I finally want to get it fixed.) Although I have found several similar posts, none of the answers appears

Hello, I would like to know what it means, when the hier.part's output has a data frame of a negative independent contribution for variables (?IJ) and how this can be caused. Thank you very much. Yours sincerely M. Heuner

Ulrike, if you install from source, you always get the most recent version of the package given it does not depend on a newer version of R. If you want a binary package, you also get the newest version - that was newest at the time we stopped building binaries for that version of R. We (or better I if we only talk about Windows, but similar for all other platforms) cannot build for each R
