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 got a probleme with R CMD check. I run a package.skeleton on a very simple code (four toy function, no probleme with the R CMD build). But on the R CMD check packClassique, I get : * checking for unstated dependencies in R code ... WARNING Erreur dans .find.package(package, lib.loc) : aucun package nomm? 'packClassique' n'est trouv? Calls: <Anonymous> ->

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

Hello the list, I am trying to write a "cleanProgramming" function to test the procedure I use. For example, I want to be sure that I am not using globals variables. The function "findGlobals" detect that. To list the globals used in function "fun", the syntax is : "findGlobals(fun,FALSE)$variable" My problem is that I want to use it in a function,

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 devel list, I am using K means with a non standard distance. As far as I see, the function kmeans is able to deal with 4 differents algorithm, but not with a user define distance. In addition, kmeans is not able to deal with missing value whereas there is several solution that k-means can use to deal with them ; one is using a distance that takes the missing value in account, like a

Hi the list. I try to learn the S4 programming. I find the wiki and several doc. But I still have few questions... 1. To define 'representation', we can use two syntax : - representation=list(temps = 'numeric',traj = 'matrix') - representation(temps = 'numeric',traj = 'matrix') Is there any difference ? 2. 'validityMethod' check the

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 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 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 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 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 define a class A (slot a and b), a class C (slot c and d) and a class E that inherit from A and B. I define print(A) and print(B). For print(C), I would like to use both of them, but I do not see how... Thanks for your help...

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

Hi the list, I need to compute Gower distance between a specific individual and all the other individual. The function DAISY from package cluster compute all the pairwise dissimilarities of a population. If the population is N individuals, that is arround N^2 distances to compute. I need to compute the distance between a specific individual and all the other individual, that is only N
