[Version fran??aise plus bas] To the R community, A quick word to announce the publication of my document "Introduction ?? la programmation en S". It is available in the French section of the Contributed Documentation page of CRAN. Many of the documents or books currently available on S-Plus and/or R present the software in a statistical analysis context. My document rather focuses

Dear R developers, I'm a former APL programmer. In that language, the "take" (up arrow) and "drop" (down arrow) operators were extensively used to, well, take and drop elements of vectors. Functions head() and tail() are equivalents in R for the "take" operator, but nothing seems to mimic the "drop" operator. I think it would be useful. For

I updated my modified GNU Emacs for Windows release to the now current version 22.2 of Emacs. The distribution is available at http://vgoulet.act.ulaval.ca/en/emacs For those hearing about this distribution for the first time, here's a short description: ready-to-install version of GNU Emacs 22.2 for Windows (released March 26, 2008) with the following additions: * ESS 5.3.6; *

[Sorry for cross-posting in an attempt to reach as many interested parties as possible.] Users (present or future) of GNU Emacs and ESS on Windows might be interested in my distribution of an easy to install (read: with an installation wizard) version of GNU Emacs 21.3 with the following additions: * ESS 5.3.3 configured to work with the latest stable release of R; * AUCTeX 11.84; * Aspell

Hi, I've got a File name too long problem using rsync-2.5.6 or rsync 2.5.5-0.1 (debian) I had a look to the mailing list archive and to the todo file and all I've seen was that the problem only appears on old special systems. I'm using debian 2.2.20. (is it too old?) I've already posted this bug in debian bug tracking system

I created a type of object similar to a data frame. In some circumstances, It needs special methods for "[" and "[<-" and rbind() (but not cbind()). Then I found this in the cbind()/rbind() man page: The method dispatching is _not_ done via 'UseMethod()', but by C-internal dispatching. Therefore, there is no need for, e.g., 'rbind.default'.

Dear developeRs (and other abuseRs ;-), I would like to contribute a patch against functions head() and tail() of package utils to allow for a negative 'n' argument. This allows to extract all but the first/last 'n' elements/rows/lines of an object, similar to the "drop" operator of APL. [1] I put the patched head.R and head.Rd files, along with diff files in

Package grDevices has a function cm() to convert from inches to centimeters. Its definition is: cm <- function(x) 2.54*x As far as I can tell, the function is not used anywhere in the R sources (I grepped for "cm(", "cm)" and ", cm".) I did not check for all packages on CRAN, though. May I propose to remove this apparently useless function from the sources? [I

Hi all, Is there an option in Sweave to avoid it from stopping on a code chunk with an error? (I purposefully want to include code with an error in class notes.) I suspect the answer is "no" and that I will be pointed to options("error"). That'd be fine, but which error parameter will just "do nothing" in case of an error? Thanks in advance! -- Vincent

Dear developeRs, Compilation of the latest version (0.9-5) of my actuar package fails with r-release MacOS_X ix86 on CRAN; see http://www.R-project.org/nosvn/R.check/r-release-macosx-ix86/actuar-00check.html All errors come from accented letters in comments in latin-1 encoded files (except hierarc.R which is in UTF-8, my bad). Encoding is declared as latin-1 in DESCRIPTION. The package

Hy all, Is there a direct way to build the complete function call of an arbitrary function? Here's what I want to do. A function will build a function which will itself call a probability density function for some law given in argument to the first function: > f("gamma", 1000) will return, say, function(x, shape, rate, scale = 1/rate) dgamma(x + 1000, shape, rate,

Is there a canonical way to check if all elements of a vector or matrix are the same? Solutions below work, but look hackish to me. > x <- rep(1, 10) > all(x == x[1]) # == operator does not provide for small differences [1] TRUE > isTRUE(all.equal(x, rep(x[1], length(x)))) # ugly [1] TRUE Best, Vincent -- Vincent Goulet, Associate Professor ??cole d'actuariat

Hi, From the R Language Definition, Section 3.4.1: "If i is positive and exceeds length(x) then the corresponding selection is NA. A negative out of bounds value for i causes an error." (This is also mentioned in S Programming, footnote of page 24.) Can someone please provide an example triggering the error? Looking in src/main/subscript.c I could not find exception handling for

Hi, May I ask what are the plans for R 2.4.0 packages for (K)Ubuntu? Will Christian yet again agree to provide packages as he did for 2.3.1? I will renew my offer to contribute, if needed.

A quick note to "publicly advertise" the immediate availability of packages of R 2.4.1 for Ubuntu Dapper Drake (6.06) and Edgy Eft (6.10), straight off CRAN. >From the README: R packages for Ubuntu on i386 are available. The plans are to support at least the latest Ubuntu release and the latest LTS release. Currently (January 2007), these are Edgy Eft (6.10) and Dapper Drake

Hi all, Just a quick note to bring to all Ubuntu users on i386 that the packages for R 2.5.1 (and a few recommended packages needed rebuilding) are now available from CRAN. Supported distributed are Dapper (6.06), Edgy (6.10) and Feisty (7.04). Please report any problems to me and/or this list. --- Vincent Goulet, Associate Professor ?cole d'actuariat Universit?
