Hi, Does anybody know a function to simulate a Markov chain given a probability transition matrix and an initial state ? Thanks.

Dear developers, I have noticed difference in computation time for the data.frame function between R2.9.0 and R2.8.1. The older release is more efficient: typically, R2.9.0 spends three more time in the data.frame function. Therefore, when many calls of this kind is done inside a function, the additional time spent with R2.9.0 may be several minutes. Looking at the profiling results (see file

Hello, I would like to write in a variable the following string : Hello "World" If I do cat("Hello ","\"World\""), I have the good result on the screen but it can not be affected to a variable. If I do the same thing with paste paste("Hello ","\"World\"") it does not work since \" seems to be not recognized. So what

Dear R developers, I had some problem when building package: for exemple when building the package e1071 available from CRAN, I get the following message error: * checking for file 'e1071/DESCRIPTION' ... OK * preparing 'e1071': * cleaning src * running cleanup * creating vignettes ... ERROR /usr/lib/R/bin/texi2dvi: pdflatex exited with bad status, quitting.

I am trying to use the function aggregate with the median function but I get the following error: Error in FUN(X[[1]], ...) : Argument "INDEX" When I replace median by mean, it works perfectly Can someone tell me where the problem comes from? Thx I am running R 2.0.0 on SunOS 5.9 -- Philippe Hup?? UMR 144 - Service Bioinformatique Institut Curie Laboratoire de Transfert (4??me

Hi, I need to computed the GSVD of two matrices. For doing so I used in my C code the lapack routine dggsvd. But when I source my file gsvd.R I have the following error: Error in eval.with.vis(expr, envir, enclos) : BLAS/LAPACK routine 'DGGSVD' gave error code -1 Is there a problem with the parameters passed through the gsvd.R script? Is there a problem within the C script?

Hi, I would like to get from a plot the size of the symbols plotted. Imagine I have the following plot function : plot(1:2,1:2, pch=15, cex=4) I would like the get the values SIZE1 and SIZE2 so that if I plot the following rectangle : rect(1.5,1.5, 1.5+SIZE1, 1.5+SIZE2) then the size of this square is exactely the same as the one of the symbols that have been plotted. Thanks for any idea. --

Hi, I would like to plot a graph on the jpeg device for example and to write a table associated to this plot where I have the pixel coordonates of each plotted point so that I could include the jpeg image onto a html page and get all the information about each point when the mouse button is pressed. The indentify() can do it but on the window device... Thanks for any idea. Philippe --

> Well, that is in all good texts on R, together with the > solution: drop=FALSE. See ?"[" for the on-line details. OK. Thank you a lot. Now patched cclust and clustIndex work fine for 1D case. BTW, why not to apply the "drop=F" to these functions? I guess other users need 1D case as well. kind regards, Valery A.Khamenya

Hello, my data is an ordered list of observations where each observation is either of condition "efficient" (coded as 1) or "non-efficient" (0) as e.g. No. Obs Condition 1 1.1 0 2 1.2 1 3 1.4 1 4 1.5 0 5 2.5 1 etc. My goal is to plot a single line with lty='o' but different symbols for either condition whenever condition is 1 or 0, i.e. on the x-axis the

Hi. I have a problem with the default behavior of seq(), which gives the argument "from" when the argument length.out = 1. This behavior is annoying when the number of value determine in length.out is not predictable. Would it be possible to add an argument that propose the median/mean, i.e. (from + to) / 2 when length.out = 1 ? Examples: > seq(from = 1, to = 11, length.out=1) #

Thanks for your answer. The rational behind my proposal is why taking "from" when length.out=1, more than "to" or "NA", or " integer(0) " ? This question seems basic. But is is not in certain situations, like when length.out = unpredictable positive integer. And I haven't found in ?seq() the particular behavior of this function when length.out = 1.

Hi, I have the following error when building a package * creating vignettes ...

Hi. I have a problem with the default behavior of sample(), which performs sample(1:x) when x is a single value. This behavior is well explained in ?sample. However, this behavior is annoying when the number of value is not predictable. Would it be possible to add an argument that desactivates this and perform the sampling on a single value ? Examples: > sample(10, size = 1, replace = FALSE)

It is a sequence starting at *from* and ending wherever the other arguments cause it to end. A sequence

Hi, I have a set of data like the following: [,1] [,2] [1,] 10 2 [2,] 7 0 [3,] 1 0 [4,] 1 0 [5,] 15 0 [6,] 17 4 [7,] 4 0 [8,] 19 8 [9,] 10 2 [10,] 19 5 I'd like to aggregate it in order to obtain the frequency (the number of occurences) for each couple of values (e.g.: (10,2) appears twice, (7,0) appears once). Something cool
