Hi all, I've been trying to figure out how to superimpose a histogram on a biplot that shows the relative contribution of each axis. I have been using the NIPALS function (http://biomserv.univ-lyon1.fr/~dray/ files/softwares/nipals.R) to run principal component analyses. Here is a toy example. source("http://biomserv.univ-lyon1.fr/~dray/files/softwares/nipals.R")

Hello, I would like to have some information about acf with missing values. Let us consider this example: x=rnorm(100) x2=x x2[sample(100,10)]=NA acf1=acf(x) acf2=acf(x2,na.action=na.pass) The computation of the acf is different for the two data sets. Looking at the the code reveals that with missing values, the computation of acf takes into account the number of pairs of non-NA values (i.e.

Dear all, I would like to compute power of a square non symmetric matrix. This is a part of a simulation study. Matrices are quite large (e.g., 900 by 900), and contains many 0 (more than 99 %). I have try the function mtx.exp of the Biodem package: library(Biodem) m <- matrix(0, 900, 900) i <- sample(1:900, 3000, replace = T) j <- sample(1:900, 3000, replace = T) for(x in 1:3000)

Dear All, I would like to plot text with a box around it. I used strwidth and strheight to compute the size of the box which is plotted with rect: z <- rnorm(10) # horizontal text works plot(rnorm(10)) x1 <- 5 y1 <- 0 label <- "Label" cha <- paste(" ", label, " ", sep = "") xh <- strwidth(cha, cex = par("cex")) yh <-

Hello list, I would like to cross-compile R packages using R 2.4.0. I am working on Linux Debian and cross-compiled (windows binaries) without problems with older R version. I have used the doc of Yan and Rossini in the contributed section of the R documentation (same version of MinGW...). When I try to cross-compile R (make R), the procedure stopped and returns :

Hello list, I am writing a paper for Rnews. I use Sweave to do it. I did not find information about writing a paper for Rnews using Sweave and have some questions: - Is there a problem to use the environment 'Sinput' in the place of 'example' or 'smallexample'. It works fine but perhaps there are some technical/editorial problems ? - I have some long lines of code in

Hello list, I have found a problem (bug?) with Sweave. I hope that someone could help me.

Hello list, (PC Windows 2000, R 1.2.3) i want to compile C source file for R on windows 2000. I'm working with Metrowerks CodeWarrior for creating and compiling C files. I've see that R.lib file must be obtain with R.ddl by Visual C++. I don't have Visual C++ (and i don't want to buy it !!) but i want to obtain R.lib file. Is there a solution to my problem ??? Any help would

Hello list, I would like to know if it is possible to get output of help(foo) with Sweave. If I insert ?foo in a chunk, the console give me the help but no output is obtained in the tex file. Perhaps something to do with options ? Thanks in advance ! -- St??phane DRAY (dray at biomserv.univ-lyon1.fr ) Laboratoire BBE-CNRS-UMR-5558, Univ. C.

Hello list, i have a glm with family=binomial, link=logit but there is over-dispersion. So, in order to take into account for this problem i choose to do a glm with family=quasibinomial(). I'm not an expert on this subject and i ask if someone could validate my approach (i'm not sure for the tests) : quasi_glm(myformula,quasibinomial(),start=mystart) summary(quasi) # test t for

Hello List, i need help for eigen and svd functions. I have a non-symmetric square matrix. These matrix is not positive (some eigenvalues are negative). I want to diagonalise these matrix. So, I use svd and eigen and i compare the results. eigen give me the "good" eigenvalues (positive and negative). I compare with another software and the results are the same. BUT, when i use svd,

Dear R-Users, ade4TkGUI is a new package available on CRAN. It implements a Tcl/Tk graphical user interface (GUI) for the ade4 package. Only the most basic functions of ade4 have a GUI in this first version : classical one-table data analysis methods (PCA, COA, MCA, PCO, etc.), one table with groups of rows (BGA, WGA, DA), and two-tables analysis methods (Coinertia analysis, CCA, PCAIV).

Issue: Three WinXP Pro boxes using Offline Files disconnect from all Samba shares when a user either performs a synch or accesses a file on the share with offline files enabled. About half the time, being able to reconnect for any length of time requires a reboot of the WinXP machines. Disabling the Offline Files in Windows alleviates the problem. Background and Network

I have used the fourthcorner function as suggest by dray and legendre (model 2 and 4 then combine). I plot the combined value with plot(four.comb, type="G"). What do the colors mean? I have both grey and black bars. many thanks, Stephen -- Stephen Sefick ************************************************** Auburn University Biological Sciences 331 Funchess Hall Auburn, Alabama

Hi People Thanks to all who replied I did not word the question very well. I had a problem in compiling the binaries on one machine then moving them to another where they would not work. What I did not know then was that the semaphores were not cleared when samba 1.9.18p1 was stopped so I got a shared memory and semaphores error. Cleared it by rebooting after installing the new bins. Thanks
