R-exts.pdf discribes S3method a little bit. But I want to understand more on how it is called, implemented and when to use it. I don't find it in an R session. But I see S3method() in some NAMESPACE files. > S3method Error: object 'S3method' not found > ?S3method No documentation for 'S3method' in specified packages and libraries: you could try '??S3method' I

Hello, I've been trying to make LinkingTo work when the package linked to has c++ code. I've put dumb packages to illustrate this emails here ; http://addictedtor.free.fr/misc/linkingto Package A defines this C++ class: class A { public: A() ; ~A() ; SEXP hello() ; } ; Package B has this function : SEXP say_hello(){ A a ; return a.hello() ; } headers of package A are copied

Hi the list, In WRE (or in Rdindex), we can find how the INDEX is make, how to change it, but I do not manage to find the purpose of this file. So what is the INDEX file for?

Hello, I discovered R two years ago and thanks to the R-community I managed to write some scripts to analyze my data stored in mysql databases. The only problem is that I am the only one using R in the lab. Colleagues mainly use Matlab (but not with mysql, only with text files) but regularly come to me to get data treated with R-scripts !!!. To allow the use of my scripts by other people, my

Hi, During my recent r2sundials development, I've came across a strange test failing during 'R CMD check' exclusively on win R-devel which I could reproduce with a minimal example that I present here. The toy packages testarma1 [1] and testarma2 [2] are minimal modifications of a skeleton package produced by RcppArmadillo.package.skeleton(). They are almost identical. The first

Hi all, I am using savePlot in a loop for saving several graph but I get some graph in 553x552, some other in 1920x1119. How comes ? My data are almost all the same (same label, same xlim / ylim, almost same data. Only the color changes). I save them in bmp. Thanks for your help. Christophe

Hi the list, I am about to submit an article describing an R package to the Journal of Statistical Software but I encounter a strange behavior of LaTeX: the numbering of the figure is correct (1. 2. 3. ...), but when I make a reference to a figure, the section (or the subsection) number appears instead of the figure number. I check if this behavior occurs with the file example provide in the

Hi the list Is it possible to create an empty matrix ? I do not mean an matrix with a single value that is NA (which is not empty) but a real empty one, with length=0. I do not understand why we have length(numeric()), length(factor()) and length(character()) to zero, and length(array()) to one... Any rason for that ? Thanks Christophe

Hi the list, I used savePlot to export some eps graph but it seems that the graph file hold a bug. I include the graph.eps in a LaTeX file. Running latex is ok. But the dvi file contain some mistake, the graph overprint on some text and hide it. Then, when I try to convert it to another format, I get : Ignoring remaining special text following unkown PS operator: "SDict" Remainder

Hi all Two questions: - I would like to learn more on oriented object programming with R. Is there any tutorial for that? - Without waking up a troll, I am not very familiar with diffusion list, I am more use to forum. On a diffusion list, how can I check if someone already asks a question? I mean, I went on CRAN-R website, I find the R mailing list archive. But is there a way to search

Hi the list I have package foo0 with a big dataset 'myData'. In DESCRIPTION, if I use 'LazyData: no', then I get: - when I open a R session : memory used=20 908 - when I attach 'library(foo0)' : memory used=24364 - then I load the set 'data(myData)' : memory used=39 668 If I use LazyData: yes', then I get - when I open a R session : memory used=20 908

Hi the list In the DESCRIPTION file of my package foo0, I have: Depends: foo1 Imports: foo2 Suggest: foo3 Enhence: foo4 If I understand correctly, to install foo0 on my computer, I need to already have foo1, foo2, foo3. foo4 is not necessary. I my R sesssion, when I will write: library(foo0), then the package foo1 will be attach. foo2, foo3 and foo4 will not. Is that correct? But what is

Hi the list, Using misc3d, we can export 3d dynamic graph in pdf format. Is it also possible to export these graph into a format that we can publish on the web?

Hi the list, I am a member of the organizing comity of the French Statistics Association (SFdS)'s conference. We are looking for sponsors. Some software (SAS, RITME, ...) are represented. Do you know if there is any possibility to be sponsored by R (or by an association close to R)? Do you think I can ask to the R fondation? Sincerely Christophe -- Christophe Genolini Maître de

Hi all, In the package rtlu, I use the function savePlot. It is convenient since it let the user decide in which graphic format he wants his graph to be export. But when I run R CMD check, I get the following message : > rtlu(V1,fileOutput="First.tex",textBefore="\\section{Variable 1 to 3}",graphName="V1") Error in savePlot(filename = nomBarplot, type = type)

Hi the list, I am writing a package in S4 and I do not manage to understand a bug. The "R CMD check" and the "R CMD build" both work. Here is links to the package (not on CRAN yet for the raison that I explain bellow): http://christophe.genolini.free.fr/aTelecharger/kml_0.5.zip http://christophe.genolini.free.fr/aTelecharger/kml_0.5.tar.gz Then I install the package and I

Hi all, In my package, I define some constant. In the previous version of R, I just define then in "/data/constants.R" but it seems that it is no longer possible. Instead, I am asked to "define them in the namespace". I am not sure to understand what it means. Shall I define them in the NAMESPACE file? Christophe

Hi the list, One of my package has a memory issue that I do not manage to understand. The Memtest notes is here: <http://www.stats.ox.ac.uk/pub/bdr/memtests/valgrind/kml-Ex.Rout> Here is the message that I get from Memtest --- 8< ---------------- ~ Fast KmL ~ ==27283== Invalid read of size 4 ==27283== at 0x10C5DF28: kml1 (kml.c:183) ... ==27283== by 0x10C5DE4F: kml1 (kml.c:151)

Hi all, I am using Sweave to produce a document. Unfortunately, I have to print several copies and I can't print them in color. So I would like to change the way of printing the code. I would like to print the code in a box with a black borderline and a grey background (quite classic). Is it possible to do it by changing some Schunk options? Christophe

Hi the list I define a S3 function that can have a various number of argument using '...' When some arguments are missing, I would like to give them some default value: func.numeric <- function(x,...){ if(missing(y)){y<-3} } But it does not works... I precise that I can not put 'y' explicitly in the argument list since func is an S3 function, I cannot change its
