Hello R-user, sorry for this very off-topic question. But I shall present R to my dept. (pro's and con's and what it can do). The pro's and con's are easy but not what R can do (additional to the "normal" statistics). I looked through the packages, but the enormous amount of packages makes it very difficult for me to decide which one is worth mentioning. I used

A colleague has just passed me this interesting address: http://cc.oulu.fi/~jarioksa/softhelp/vegan.html "Vegan: R functions for vegetation ecologists" "Vegan package is intended to help vegetation ecologists and other community ecologists to use R.

Dear Colleagues, We are using the phylog.gls.fit() function from the R package "PHYLOGR" (Diaz-Uriarte R, Garland T: PHYLOGR: Functions for phylogenetically based statistical analyses. 2007. Available at [http://cran.r-project.org/web/packages/PHYLOGR/index.html]) to correct for lack of independence between data points. (In our particular case, the lack of independence is due to

Hi, I would like to announce the first version of GraspeR. It is a port of GRASP (Generalized Regression Analysis and Spatial Predictions) written for S-Plus, to R. It serves as an "automated" method for doing spatial predictions. You can find the first testing version at http://www.fivaz.ch/grasper/index.html. For now, I provide a dump file you can read with source(). A UNIX package is

I have JUST started using R. I am using R 2.0.1 on a mac (os x) to run another program (called GRASPER, Generalized Regression Analysis and Spatial Prediction for R). When I try to run Grasper, I get an error for tcl/tk: > library(grasper) Loading required package: mgcv This is mgcv 1.1-8 Loading required package: MASS Loading required package: tcltk Error in dyn.load(x,

Hi All Please see the Rprofile file which i have modified as follows and after that when I start R then I see that R says to me "TRUE" for all the packages implying that all loaded at once. But when i try to use commands as simple as help("lm"), it doesnt work nor any of the menu "Packages" is not working. Although the regression using lm ( Y ~ X ) is working

Hello R user, I downloaded grasper_0.3-2.tar.gz and installed it as described. $ su $ R CMD INSTALL grasper_0.3-2.tar.gz $ R that seems to work, but > grasp.GUI() doesn't work. I read the note, that graspeR need mgcv (downloaded), MASS, modreg and tcktk . I haven't found the last 3 packetages in the Suse 8.1 contrib list. Where can I find them? Or what could be the problem? thanks in

Dear All, A library (PHYLOGR) that passed the usual tests in R-1.1.1 gives errors with R-devel; my (mis?)understanding of scoping rules is that it should have worked in both. The problems seem related to using the name of the data frame for extracting weights or subsets within a function call. The problems can be reproduced as follows: ********************** datai <- data.frame( y =

The report on R_help about problems loading package irr (in a UTF-8 locale, it seemed) prompted me to look a little deeper. There are quite a few packages with Latin-1 chars in their .R files, and a couple in UTF-8. Apart from non-ASCII chars in comments, this is a problem as the code concerned cannot be represented in some locales R runs in (for example Japanese on Windows). It happens

I have build R-1.6.0 on Jaguar (actually on 10.2.2), using gcc 3.1 from Apple, g77 3.1 from fink, ATLAS from fink. It passes all checks OK. I also re-compiled the 233 packages listed below with the same setup. I have NOT tested all these packages in any detail. A tar.gz file with the whole /usr/local/lib/R will be on ftp://gifi.stat.ucla.edu on Tuesday. It will NOT include anything from fink

Hello... I tried to build R-devel today on Fedora Core 1 (with gcc 3.3.2) but I am running into a couple of errors. On the same system R-1.8.1 compiles just fine, as did a previous version of R-devel. This is what I did: # change LANG as default in FC1 is UTF-8 export LANG=en_US.ISO8859-1 export LANGVAR=en_US.ISO8859-1 # get fresh sources and configure mkdir R-devel rsync -vrC
