Dear all, I am having a problem using grid when rotating a viewport. It seems to plot everything on a grey background colour which I am not able to get rid of. Even book examples such as that that plot figure 5.10 in P. Murrell's R Graphics book show the same behaviour. The following example illustrates this issue. I would appreciate if anyone has a way to solve this. Best regards,

Dear All, I am trying to find a way to plot a dendogram in reverse, that is, if the terminal leaves are labelled 1-10 bottom to top (or left to right), I would like to be able to plot it in a way such that if would display 10-1 bottom to top or left to right. Any idea how to achieve this? Thanks in advance, r. Dr. Rafael Najmanovich European Bioinformatics Institute Wellcome Trust

Dear community, I am writing a wrapper for '[' operator, which is a generic method declared as function(x, i, j, ..., drop). It turns out that I need to parse the '...' argument and this is where I am stuck. Generally what I need is the following. Say the call is obj[1, 1, 1:10, 3] - here '1:10, 3' is passed into '...'. What I need to evaluate that '...'

Dear community, this is just a suggestion, but might be useful for the following R releases. I was programming some C code for R and my compiler constantly showed me some crazy messages that a stdc++ macro length() was supplied with 4 arguments whereas only one was required. The problem could be partially resolved by changing the order of includes. However as soon as the file was used from

Dear all, the 'inline' package was updated to version 0.2.2 with the following changes: - functions declared using 'cfunction' can now be saved, the code is recompiled when the object is loaded (not yet implemented for setCMethod) - full path to the R binary is used for compilation allowing for the use of the correct R version when several are installed The

Hi everyone It looks like repeated runs of fastICA produce quite significantly different mixing matrices (not only in terms of sign and row order). I'm not a specialist, so would appreciate any advice on whether this should really be the case: > res3 = > fastICA(af[,2:20],4,alg.typ="parallel",fun="logcosh",alpha=1,method="C",row.norm=TRUE) colstandard >

Dear lists: I am somewhat puzzled by the use of texi2dvi/pdflatex in R2.7.0. When building EBImage (bioconductor) with 2.7.0 I get the same error both in Windows and Linux, which reads the following: ** building package indices ... * DONE (EBImage) * creating vignettes ... ERROR /usr/bin/texi2dvi: pdflatex exited with bad status, quitting. Error in texi2dvi(file = bft, pdf = TRUE, clean =

Hi, I do not know if everybody finds index pages of the html-formatted R help useful, but I know I am at least not the only one who uses them extensively to get the overview of functions and methods in a package (even for my own package). Problems arise, however, if a lot of S4 methods need to be documented blowing out the index with (generally irrelevant) entries like:

Dear R developers, I am writing some C code that loads multiple images into a list of R matrices. The whole R object is created within the C code. To simplify coding, elements of the list are first created as vectors and then converted to corresponding matrices using setAttrib(x, R_DimSymbol, s). Generally the code works fine except for one detail. Applying setAttrib sets ALL elements

Dear All, I have never had this problem before. I run debian testing on my box and I have recently update my R environment. Now, see what happens when I try the most trivial of all plots > plot(seq(22)) Error in (function (display = "", width, height, pointsize, gamma, bg, : X11 module cannot be loaded In addition: Warning message: In (function (display = "", width,

This is a question and maybe an announcement. We've been discussing in the group that it would be nice to have a mechanism for something like "inline" C/C++ function calls in R. I do not want to reinvent the wheel, therefore, if something like that already exists, please give me a hint -- I could not find anything. If not, here is a working solution, please criticise so I could

Hi Community, I have a question about how to pass command line parameters to R script running in the batch mode. The problem is: there is a banch of data files which are to be processed by R script called from a web-server, i.e. in the batch mode. The web server generates data files and passes their names calling 'R CMD BATCH' one by one for every file. Now the question is how to

Dear R developers, I've just encountered one "feature" of R-C extensions. If it is known, I would be thankful for any hints why it works this way (I found the way around, which is also mentioned here, but maybe it is not the best one). If it is however unknown, it might be considered for a "wish list". Consider a simple "aka" C function (the original

Dear developers: I have just came across an (unexpected to me) behaviour of lists when assigning NULLs to list elements. I understand that a NULL is a valid R object, thus assigning a NULL to a list element should yield exactly the same result as assigning any other object. So I was surprised when assigning a NULL in fact removed the element from the list. Is this an intended behaviour? If

I don't have my debian box available so can't confirm. But I would try $apt-get install libpng On Tue, Apr 19, 2016 at 11:23 AM, Lorenzo Isella <lorenzo.isella at gmail.com> wrote: > Dear All, > I have never had this problem before.

Dear John Fox and everyone, I have been using the effects library with glms and have found it very useful. Now I'm trying it with lms and I'm not sure if the results of the allEffects() are as expected. I've got a model that looks like this: mymodel = lm(formula = A ~ B + C + D + B:D + C:D) Residuals: Min 1Q Median 3Q Max -3.80156 -0.73486 -0.09792

Hi Community, here is the problem, Linux problem (reported to work on Windows). I need to generate graphical output in any of bitmap format under the 'R CMD BATCH'. Whereas the script generating png-s works perfectly in the R session, such things as X11, png and jpeg are not usable in BATCH (they cannot be switched on by --gui-X11 etc) and X11 is prompted to be required for png.

Dear developers, has anyone experienced the problem described below? Is it a bug in handling interrupts in R?

Any idea why CHAR(asChar(STRING_ELT( produces NA whereas CHAR(STRING_ELT( gets a pointer to a string? It's generally expected that STRING_ELT should already be a character, but why the coercion does not work? Here is a simple example (consistent over R2.5.1-R2.6 rev 42284, I didn't check earlier versions, but it used to be different in 2.4): install.packages("inline")
