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

...or of more than 40 000 ID and the function I wrote (it orders my data and checks on ID:Name of the data if the next term is the same as the previous one (see below) ) is really slow (30minutes for 44290 terms). But I don't have time by now to write a C function. Thanks a lot for your help, Laetitia. Here is the function I have written maybe I have done something not optimized : repVector <- function(obj){ # order IDName ord <- gif.indexByIDName(obj) ordobj <- obj[ord,] nspots <- nrow(obj) # vector of spot replicates number spotrep <- r...

...that is a loop: a <- as.character(dat[(2x-1),1]) b <- as.character(dat[(2x),1]) for (i in 1:length(dat[,1]) my_function(a, b)) Can somebody help me to apply a function with a loop in the way I want to a column? Is there a specification of "tapply" for that? Thank you very much, Laetitia ---------------------------------------------------------------------------- Laetitia G.

...his output and want to calculate things, R complains that x is not numeric. I read it in with the following command: dat1<-read.table("temporary_output.txt",header=TRUE). It seems that R is saving my temporary output as a list. What is here wrong? And how can I do it better? Thanks. Laetitia

...ParasiteC 2 1 1 3 ParasiteD 2 1 1 4 ParasiteE 4 1 1 1 The function should give a 1 for plots 1 and 4 and a 0 for plots 2 and 3. Your help is very much appreciated, Laetitia

...ee 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.

...nt 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, What am I doing wrong? Thanks Laetitia

...can I specify in tcltk file browser the initial directory to "MyComputer" in Windows where Drives and Partition are accessible? And just a little question if anyone knows, is there a way to use the function choose.files under windows to select a directory? Thanks a lot for your help. Laetitia.

...mpletion 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 ideas?? Thanks for you help, Laetitia.

Hi, Can anybody show me how to extract all columns in my dataset that are polymorphic? Or phrased in another way I would like to delete all columns that have no more than one letter in it (that are monomorphic). Thank you.

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.

...the connection and from you java code it is as simple as this example: REXP mean = c.eval("mean"+i+"<-apply("+data+"[,data.cl=="+(i-1)+"],1,mean.na)"); This is what I'am using in my application and I am quite satisfied with it.

Hi Everyone, This is my first message on this discussion list. I create a R function which includes a .C function. I didn't get any error neither from "C side", nor from "R side". I tried to put proper type in R. But the problem is that I get an abrupt closure of R, with the following message: " R for Windows GUI front-end encountered a problem and needs to

Hi, I am sampling two random columns from females and two random columns from males to produce tetraploid offspring. For every female I am sampling a random male. In the end I want to write out a a matrix with all the offspring, but that does not work. I get always only the offspring from the last females. There must be a mistake in my script: moms<-read.delim("females.txt",
