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 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 devel list I am testing package.skeleton in R 2.7 (download today). I get an error that I do not understand. I guess it is not an error from my code since I have no probleme when I source it. So is it a error in package.skeleton? Here is my code : --- 8< ------ File essai.r ------------- setClass( Class="ClusterizLongData", representation=representation(

Hi the list, I need to use getGraphicsEvent to plot two graph. On the following toy example: - the function b is ploting two graph depending on a parameter - the function a is calling b according to some user answers. It is suppose to call b until the user press Return, but it does not. b <- function(x){ dev.off(2);dev.off(3) windows();windows(3,3,xpos=0) dev.set(2);plot(1:x)

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. Is there a bug in mmlcr package ? The following code does not compile: mmlcrTest <- function(dataW){ dataL <- reshape(dataW,idvar="id",timevar="T",varying=list("T0","T1","T2"),direction="long",v.names="score") resultR <- mmlcr(outer= ~ 1 | id, components = list(list(formula =

Hi the list, I guess I find an other bug (the first one is at the end off this mail) in package.skeleton. It occurs when we give as code_file some file that are not in the current directories. If we give a single file to code_file (like code_file=3D"riri/fifi.R"), it does not reconize fifi.R as a regular name and change it to riri/zfifi.R If we give several file to code_file (like

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, 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, 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

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, Considere the following: f <- function(x){apply(x,2,mean)} findGlobals(f) findGlobals consideres mean as a global variable, which it is not. Is there a way to tell to findGlobals that mean is a function ? 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 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 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 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?

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
