Dear all, I'm trying to rerun some data linkage exercises in R (they are designed to be done in SPSS, SAS or STATA) The exercise in question is to relabel the column "treat" to "1", if "yearsep" is smaller than 1988 and columns "proc1"-"proc3" contain the values 56.36 or 59.81. My pathetic solution to do this in R currently looks like

Hello, on Mon Nov 9 17:57:04 CET 2009 I've sent an e-mail to the R mailing list (see below), about a failing regression test. Yet nobody replied, while (obviously) the situation didn't change (installation still fails, and might continue to do so in the future). I wonder whether somebody has to say something here? Shall a bug report be submitted? Or will R 2.10.1 have fixed the bug?

Are there any R rpm's for Mandriva 2008.1? I found a couple of dodgy ones that wouldn't install so far (rpmfind.net). (Sorry that seems so far the only Linux distribution that recognizes my hardware on my new laptop correctly. I'm more familiar to Fedora and Suse so perhaps I'm just doing something wrong?) Joanne

Does anyone know what file type sink is outputting to? I've been reverting output from R using sink and wanted to add it to my Appendix in LaTex (Lyx) using "Verbatiminput". However, I get an error message as LaTex is expecting an ASCII file. Can I set sink somehow to ASCII or is there another option? Thanks Joanne

I am trying to download the R program, but am having trouble. I have read through the instructions, but do not seem to be able to do it properly. Can you tell me the step-by-step instructions?

Hello everyone, I'm currently trying to export a couple of graphs to pdf . Postscript would be fine too, but I'm using odd page dimensions, which seem to be overwritten when using the "ps2pdf" command. I'm using the pdfpages package in LaTeX to put 6 graphs onto one page (this is why it ought to be a pdf in the end). I have two problems: 1. I'm using

Dear all, I have been using the contrast library in my teaching for the last couple of years and am right in the middle of this year's round. In the last week R has been updated to version 2.14.0 on our computers. This has had the unfortunate effect of meaning the contrasts library no longer works, as the Design library is no longer available. I wonder if anyone has a fix for this...or

Just a quick question on LLVM, signals, and the lli interpreter. A sample program is included at the end. Platform is x86, Linux, 32-bit, GCC 4.2.4. Does lli -force-interpreter support signals, or is it only the JIT that does? The following sample program crashes with lli 2.5 and lli top-of-tree. Thanks and regards, Matt ============================= #include <stdio.h> #include

Hello, Platform is RHEL5, GCC 4.2.4, x86-32, and LLVM/LLVM-GCC from subversion (yesterday evening). I'm compiling C code into bitcode, and then executing the bitcode using the JIT compiler (lli). I've managed to reproduce a problem when multiple signals go off around the same time. A sample program is below. The result is the "recursive compilation detected" JIT compiler

Hello, I just updated from R 2.1.1 to R 2.3.1 (I also updated from Fedora 3 to Fedora 4 if that is of any importance). However, several packages (e.g. fields etc.) refuse to be installed. I get the following error message: [root at localhost R-files]# R CMD INSTALL fields_2.3.tar.gz * Installing *source* package 'fields' ... ** libs g77 -fpic -O2 -g -pipe -m32 -march=i386

I have a data set with 50 different x values and 5 values for the sampling variance; each of the 5 sampling variances corresponds to 10 particular x values. I am trying to fit a mixed effect linear model and I'm not sure about the syntax for specifying the fixed variance structure. In Pinheiro's book my situation appears to be similar to the example used for varIdent, where there is a

Hi, I'm having trouble using the constrOptim function to generate the 9-component vector argmin of the function ELfsds: ELfsds <- function(pvechat){ LG=0 for(i in 1:9){ LG=LG+log(pvechat[i]) } return(-LG) } with accompanying gradient function: gradfunc <- function(thetavec){ g=1/(9*thetavec) return(g) } The constraints on the optimization problem are: 1 - components of

Dear all mailing listers, Does Anyone have the same problem as mine when using the fast99 (extended-FAST method) to perform SA of model with norm distribution inputs? See the simple example given following. Any suggestion will be greatly appreciated. Thank you!

Hello, I would like to do a partial least square discriminant analysis (PLSDA) in R using the package "ropls" Which is in R available via the R command : source("https://bioconductor.org/biocLite.R") When I try to do a PLSDA using my own data. The impact of two genders (AP,C) on 5 compounds measured in persons (samples) should be illustrated. When I try to do a PLSDA I get

We have CENTOS 5.3 on DELL server.
