Hello, Is there a simple and fast function that returns a vector of the number of replications for each object of a vector ? For example : I have a vector of IDs : ids <- c( "ID1", "ID2", "ID2", "ID3", "ID3","ID3", "ID5") I want the function returns the following vector where each term is the number of replicates for the

Hi, I have R installed under a Mandrake linux system and I don't have shell utilities any more under my R console such as completion when writing a file path, back and forth in the history, bindkeys... Moreover when I quit R by saving, no .Rhistory file is created while the .Rdata is. I don't get how this work, I thought it was based on the user unix shell but it does not seem. Any

In the previous versions of R (2.6.1), when a vector of NA was given to the functions 'sd' or 'var' with parameter na.rm = TRUE, it used to return NA. Now (2.7.1) it returns an ERROR : Example in 2.6.1: > sd(c(NA, NA, NA, NA), na.rm = TRUE) [1] NA Example in 2.7.1: > sd(c(NA, NA, NA, NA), na.rm = TRUE) Error in var(x, na.rm = na.rm) : paires d'éléments

Hi everyone, I want to write a function that modify directly variables passed as parameters (the equivalent in C language of *ptr/&ptr) so that I don't have to return a list and to reaffect all my variables. Is it possible to do so in R? Thanks a lot. Laetitia Marisa.

Hello, When I launch a script under windows it does not display sequentially my cat calls or maybe the console is not refreshed at every line of my script. For instance with that code cat("\n\n================== IMPORT DATA FROM FILE ===================\n\n") fileschosen <- choose.files(caption="Select gpr files", filters = matrix(c("genepix

Hi! Does anybody know a string function that would calculate how many characters two strings share? I.e. ("Hello World","Hello Peter") would be 7. Thanks. Laetitia

Hello All, I am having a very strange problem with samba 3.0.23c. I upgraded everything from 3.0.9 and I am able to smbclient to the samba 3.0.23c PDC with the administrator user just fine. When I go to add a machine to the domain, it adds the unix machine account to the ou=computers like it is supposed to but none of the samba entries are added. I get an error on the windows side of

Hello, the admonition of Prof. Ripley to search the documentation to solve my problem helped, today I read a lot more on Tcl/Tk than before ;-) But now I'm stuck again. With the help of my script some functions are plotted on the display, then I ask if the user wants to save it as pdf. In windows I use winDialog and it works. But I can't succeed in Linux. In short:

Hi, I've had a little problem for several weeks now. It is annoying and therefore I will ask for help now: When I write a script with several iterations, I make it write out a text file to save the data during the run. For example I write: if (i %% 25) write.table(output,"temporary_output.txt") Later on, when I read in this output and want to calculate things, R complains that

Hi R people! I am looking for some suggestions writing an if-else function. The idea is to characterize different plots containing counts of variables (here parasites). If a plot has a count equal or higher than 4 for any parasite the function should return a 1 else a 0. Later I can loop the function over all plots. Here I have a little subset of my data: VariablePAR Plot1

R-2.8.0 / tcltk8.5 In windows, Rgui.exe has a directory browser that can be resized, but when I call tkchooseDirectory(), it is a fixed size. In linux, when I call tkchooseDirectory() it can be resized. How do I get a windows version that I can resize? [[alternative HTML version deleted]]

Help! Being a bit of a novice, please bear with me if this is a stupid question! I am trying to fit a saturated model to some count data that I have: model<-glm(COUNT~SP*LOC*COL*TIME*TREAT,poisson) but R keeps on crashing and coming up with (occasionally before crashing) an error that states: Algorithm did not converge in: (if(is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y,

OK I have been trying to learn how to use this program and I cannot even import any data into it. I have downloaded all the manuals but they do not seem to help. Is there a book on R for dummies???

Dear R users, I am trying to fit a glm with a distribution free family, link = log and variance = constant*mu. I guess I have to use the quasi family but the choices of variance are restricted to constant or mu or mu^2..., I don't know the way to choose the variance that I need, i.e. constant*mu. If you have any ideas or advice, please tell me. Thanks, Laetitia Mestdagh Laetitia Mestdagh

Sorry for the cross-post. Not sure where the problem is... A while back I posted an R function to R-help: cd <- function (dir = tclvalue(tkchooseDirectory()), saveOld = FALSE, loadNew = TRUE) { stopifnot(require(tcltk)) if (saveOld) save.image(compress = TRUE) setwd(dir) rm(list = ls(all = TRUE, envir = .GlobalEnv), envir = .GlobalEnv) if (loadNew &&

I was trying to install ferret 0.9.2 on solaris (SunOS 5.8) which does not have a sys/dir.h nix_io.c:5:21: sys/dir.h: No such file or directory make: *** [nix_io.o] Error 1 I couldn''t find an obvious way around this... any suggestions?

I am trying join a w2k bo to a samba DC on RH9. I have read that I need to add the computer as a user first then join so I did it via these commands: adduser myComputer$ smbpasswd -a -m myComputer Is that all i need to do? When I join I get the "welcome to the domain message" and then I restart. However when trying to login I get "This systems computer account is not in the

How on Earth can I know what are the arguments of any of the functions of the tcl/tk package? I tried hard to find, using all search engines available, looking deep into keywords of R, python's tkinter and tcl/tk, but nowhere I found anything remotely similar to a help. For example, what are the possible arguments to tkgetOpenFile? I know that this works: library(tcltk) filename <-

Hello World, I have a function that makes pairwise comparisons between two strings. I would like to apply this function to my data (which consists of columns with different strings) in the way that it compares the first with the second entry, and then the third with the fourth, and then the fifth with the sixth, and so on down each column... So (2x-1) and (2x) would be the different entries to be

Hello, I'm very new in working with tcl/tk in R and have a problem which will probably sound silly to most of you. Here is the code I have problems with: readcelfiles <- function() { require(tcltk) tt <- tktoplevel() tkgrid(tklabel(tt,text="Choose a directory!")) OnOK <- function() { fileDir<-tclvalue(tkchooseDirectory()) data.raw <-
