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, 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 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 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 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 do not understand the philosophy behind numeric and integer. - 1 is numeric (which I find surprising) - 2 is numeric. - 1:2 is integer. Why is that ? Christophe

Hi the list, I build a package. They was a mistake in it, but R CMD check did not find it. Is that normal ? Here is what Kurt gets (which is right, I did this mistake): --- 8< ---------------- * checking for code/documentation mismatches ... WARNING S4 class codoc mismatches from documentation object 'LongData-class': Slots for class 'LongData' Code: id other time traj

Hi all Is there any compiler for R ? By compiler, I mean something that check the cleanliness of the code : if we declare all the variables we use, if we don't use external variable from a function and so on... For exemple, something that will ring a bell on the following code (saying "line 4 : 'pp' undefine in function 'power' ") 1. pp <- 3 2. power <-

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

Hi the list When two setGeneric occurs on the same function, the second erage the first and erase all the function previously define. Is it possible to prevent that ? Is it possible to declare a setGeneric that can not be erased later ? Something like the |sealed for setMethod...| || |Thanks| || 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 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?

Hi the list, I have some basic questions about "writing a package". On which list shall I post them? Theoretically, I am supposed to post them on r-devel, but all the questions on this list are very advance questions, not basic ones... So I don't know what to do.

Hi the list, I write a package for clusterizing longitudinal data using a non parametric algorithm. I develop the package under windows. To be as user friendly as possible, the package use some graphical procedure to "show" to the user the evolution of the cluster construction, and to export the graph in a friendly way. Here are some example : http://christophe.genolini.free.fr/kml

Hi all I define a function with two methods, one for numeric or integer. Sometime, I need the numeric method to be applied on integer. So I try to change the class of the integer but it does not work... Does someone know why ? > x<-1:3 > class(x) [1] "integer" > class(x)<- "numeric" > class(x) [1] "integer" Thanks Christophe

Hi all I am working on k-means algorithm (in R: kmeans( ) ). The R-help advice us to try several random start in order to avoid local minimum. Does one know if there is a procedure that automaticly run this rerolling and select the best partition ? Or any studies that gives clues on the number of rerolling ? Thanks for helping. Christophe

Hi the list, I almost finished the green book (chapter 7 and 8 on S4), this is probably one of my last question :-) I hope you will not miss them to much ! Here is my today nighmare: I do not manage to use dumpMethod : setClass("A",representation(a="numeric")) setMethod("plot","A",function(x,y,...){cat("AAAAA\n")})

Hi the list, Using S4, how can we create a package? In "S4 Classes in 15 pages, more or less", they put all the classes definition in a function that will be called at the opening of the library and they add "by hand" a Rd file. Is it the only way ? Is there something like "S4.package.skeleton"? Thanks Christophe

Hi the list, Is it possible to get the list of all the S4 user define classes? I would like to set up a "package.skeleton.S4" but for that, I need the list of the classes... Thanks Christophe
