Dear Friends, I'm contributing to a paper on a new R package for a clinical (medicine, ophthalmology) audience, and part of the mission is to encourage people who might be occasional users of Excel or SPSS, to become more familiar with R. I'd really appreciate any pointers to more recent papers that describe R, it's growth (statistics on user base, number of packages, volume of help

Hi. I'm not having any luck installing the binary for the new Macintosh OS called "Tiger". I get error messages as below. Can anyone offer me some advice? (PS: I checked the bug list first but a search on "Tiger" turned up nothing so I hope it's OK to post here.) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared

Hello friends. I've just switched from linux to osx, and I'm liking it, except now that I'm getting down to brass tacks, and needing to install some R packages, I'm at a roadblock. I'm hoping someone can help. My R is installed from a .dmg, and resides as follows: $ which R /usr/local/bin/R The problem is that I cannot build packages. For example, see the below (which

Using R 1.8.1, and the negative binomial glm implemented in MASS, the default when using anova and a chi-square test is to divide the deviance by the estimated dispersion. Using my UNIX version of S-plus (v 3.4), and the same MASS functions, the deviances are *not* divided by the estimated dispersion. Firstly, I'm wondering if anyone can enlighten about the correct procedure (I thought

Trevor, Thanks for your reply. That doesnot help Any other suggestions?

I've been using (and loving) R for quite a while now, but I have to admit that something simple is still stumping me. The question is how I can control the box within which a plot is drawn, in cases where I'm controlling the aspect ratio with the "asp" argument. The problem comes up in pdf() and png() output formats, but also with interactive windows, and so I'll

Hello. I'm having difficulties getting R_alloc() to work. The test platform is a 64-bit Mac running R 2.2.1 installed via a .dmg file obtained from the R site. Details are given below, in a level of detail that I hope is appropriate. My eye was particularly drawn to line #2 in the gdb 'where' output, but line #1 seems sensible so I may just be displaying my ignorance by

I'm estimating two models for data with n = 179 with four clusters (21, 70, 36, and 52) named siteid. I'm estimating a logistic regression model with random intercept and another version with random intercept and random slope for one of the independent variables. fit.1 <- lmer(glaucoma~(1|siteid)+x1 +x2,family=binomial,data=set1,method="ML",

I have never used -> but I noticed at http://github.com/jiho/r-utils/blob/master/beamer_colors.R that some people do. In fact, the above-named code has a sort of elegance about it (except for the use of "=" for assignment...). To my eye, -> calls to mind a type of assignment that is meant to stand out. For example, perhaps it would make sense to use -> to assign

QUESTION: how should I do a linear regression in which there are errors in x as well as y? SUPPLEMENT: I've seen folks approach this problem by computing eigenvectors of the covariance matrix, and that makes sense to me. But I'm wondering if this has a "pedigree" (i.e. if it makes sense to folks on this list, and if it's something that has been published, so I can refer to

Hi, I am trying to run the "schools" example in the rbugs library (running winbugs in linux via wine-20041201) but keep getting the following error. Note I have tested wine and winbugs to confirm that both are operational. Error in runBugs(bugs, script.file, n.chains, workingDir, useWine, wine, : BUGS stopped before getting to coda. The command I'm using is:

I am trying to obtain some more detail regarding the nlm function available in the latest release of R. Specifically, what mimimization routine is being used... and ... does there exist a fortran or C version of it? Thank you, Joanna Joanna Elizabeth MILLS, M.Sc. Ph: (902) 494-3747 Dalhousie University Fax: (902) 494-5130 Department of Mathematics and

I have an R program which basically reads in data. It then calls a C program which performs numerical integration until converging to a solution. The result is then passed back from C to R. Unfortunately, when running this program, the virtual memory associated with it explodes -> 2GIG!. Does anyone know what might be causing this or can suggest possiblie ways to debug? Thank you! Joanna

Please excuse a question from somebody who is new to R. I'm using R version 0.90.1 (from an RPM package for redhat-linux) and am running into difficulties with code that looks like: nls(~ relative.error(..., x, y),data,start=list(...)) I've taken this code, which attempts to do a nonlinear curve-fit with weighted deviations, from section 10.3 of the book 'Statistical models in

I have a package that contains some fortran code. It has been built in the past, but now I have an updated Apple OSX 10.4 (Tiger) system, and it fails. The behaviour is as follows $ R CMD CHECK oce ,,, gcc-3.3 -bundle -flat_namespace -undefined suppress -L/usr/local/lib -o oce.so geoddist.o ocecp.o rho.o spice.o strho.o theta.o tsrho.o -

Q: Has anyone implemented cartograms [**] in R? A search on the R site turned up https://stat.ethz.ch/pipermail/r-sig-geo/2005-December/000698.html which led to http://www.okada.jp.org/RWiki/index.php?cmd=read&page=Rmap%A4%F2%BB% C8%A4%C3%A4%BF%C3%CF%BF%DE%C9%BD%BC%A8&word=Rmap#content_1_35 which has (one form of) a cartogram as a PNG, but which doesn't seem to have code. (The

Hi all, I have created forest plots using the package "meta" that I submitted as pdf for publication. I just received an email from the editor asking me if I could send these files in an Excel or MS Word format such that they can treat them as tables with box plots. I am not sure if I can do this... Is this possible? I've tried the capture.output command, but I get a blank MS Word

Hello list, I'm having a problem with custom functions in rpart, and before I tear my hair out trying to fix it, I want to make sure it's actually a problem. It seems that, when you write custom functions for rpart (init, split and eval) then rpart no longer cross-validates the resulting tree to return errors. A simple test is to use the usersplits.R function to get a simple, custom

First, let me join the chorus of praise for R. (Hey, isn't somebody going to analyse all these praise emails in some statistical way?) I'm writing to point out an error in the file permissions in the linux/redhat version. (I'm using R-base-1.0.0-1.i386.rpm, by the way.) The permissions in /usr/lib/R/doc/html aren't correct, since 'function.html' and
