I met today a computer crash and our maintenance officer had to reinstall some components of the OS (MS Windows XP Pro) as well as the Internet browser (among other things). Now, I cannot install packages from a distant repository: > utils:::menuInstallPkgs() Error in .readRDS(pfile) : unknown input format > traceback() 5: .readRDS(pfile) 4: .packages(all.available = TRUE) 3:

Dear all, I've just downloaded R.12.0 from CRAN (http://cran.r-project.org/bin/windows/base/release.htm). I am unable to find RGUI.exe as well as Rterm.exe. Conversely to what is explained in readme.R.2.12.0: There are two versions of the R executable in R-2.12.0\bin\i386 (32-bit) or R-2.12.0\bin\x64 (64-bit). I can't find directories i386 or x64 in R-2.12.0\bin -- Renaud Lancelot EDEN

Dear all, I have installed the latest version of R 2.12.0 available on CRAN (http://cran.r-project.org).

Hi, Does anyone know how to make the color of the lines all black when plotting groupedData with an outer factor: For example, library(nlme) plot(Dialyzer, outer=~QB, key=F) This generated colored curves in R.2.4.1. How to make all the curves black ? (or how to alter the color (type) of lines for the nlme groupedData plotting function in general?) Thanks Qiong

Hi, I have not been able to calculate residuals in the lme4 package. I've been trying the resid() function after I ran a GLMM with the lmer() function, but I get an error message that says "residuals are not inserted yet". I looked it up in the "help" history and I realized that several people have had this problem in the past, related to some bug in this function and

Hi, I am very intrigued by the idea of integrating statistical analysis directly with a paper as Sweave does it. But as I am collaborating with several people and they won't have set up R and also they're very unlikely interested in learning it, I am concerned about how such an Latex/Sweave document will work on their side. Can they Latex-compile the document without having R / Sweave

windows XP R 2.8.1 I would like to learn to use Sweave with R. I have no experience using Latex. I have looked at the sweave manual (http://www.statistik.lmu.de/~leisch/Sweave/Sweave-manual.pdf) and have found it difficult to understand, probably because I don't know Latex. Can someone recommend a document that will get me started with Sweave? Thanks John Confidentiality Statement: This

thanks a lot Renaud. but i was interested in Finney's fiducial confidence intervals of LD50 so to obtain comparable results with SPSS. But your reply leads me to the next question: does anybody know what is the best method (asymptotic, bootstrap etc.) for calculating confidence intervals of LD50? i could "get rid" of Finney's fiducial confidence intervals but

To Windows R users: The binary build of R that I uploaded on Tuesday contained errors in the compiled HTML help files and some of the PDF versions of the manuals. In particular, the index was missing from the CHM files, and the table of contents was missing from at least one of the manuals. I've since found the error in my setup, and have rebuilt the distribution. I uploaded it to CRAN

I am creating habitat selection models for caribou and other species with data collected from GPS collars. In my current situation the radio-collars recorded the locations of 30 caribou every 6 hours. I am then comparing resources used at caribou locations to random locations using logistic regression (standard habitat analysis). The data is therefore highly autocorrelated and this causes Type

Dear all, I have computed a digital terrain model from a set of points (x, y, z) using the function interp() in package akima. I want to predict flooded surfaces given target values of z. I can display the flooded surfaces with contour() or image(), but I don't know how to get the polygons delimiting the surfaces. Did anyone write a function for this purpose ? Best regards, Renaud --

hello I make a subroutine that give-me a (mathematical) function in string format. I would like transform this string into function ( R function ). thanks for any tips. cleber #e.g. fun_String = "-100*x1 + 0*x2 + 100*x3" fun <- function(x1,x2,x3){ return( ############ evaluation( fun_String ) ############ ) True String mathematical function :-( :-( > nomes [1]

Hi, lme() users, Can some one tell me how to do this. I model Orthodont with the same G for random variables, but different R{i}'s for boys and girls, so that I can get sigma1_square_hat for boys and sigma2_square_hat for girls. The model is Y{i}=X{i}beta + Z{i}b + e{i} b ~ iid N(0,G) and e{i} ~ iid N(0,R{i}) i=1,2 orth.lme <- lme(distance ~ Sex * age, data=Orthodont, random=~age|Subject,

Dear all, 1. How can I compute the intersecting area between 2 polygons ? 2. I have polygons with coordinates in decimal degrees (i.e. 13 deg 30 min = 13.5 decimal degrees). I want to compute their area and get the results in square meters or square kiometers. Can anyone give me a conversion coefficient or a pointer where I can find this information (sorry for this off topic question) ? Thanks
