Announce: Contributed Documentation
[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

Negative argument for head() and tail()
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

Testing if all elements are equal in a vector/matrix
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

S3 methods for cbind/rbind
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'.

Suggested tidying up
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

Small encoding question
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

Building the call of an arbitrary function
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,

Testing if all elements are equal in a vector/matrix
Hi All, There are several replies to the question below, but I think there must exist a better way of doing so. I just want to check whether all the elements of a vector are same. My vector has one million elements and it is highly likely that there are distinct elements in the first few itself. For example: > x = c(1,2,rep(1,100000)) I want the answer as FALSE, which is clear from the

Patch to allow negative argument in head() and tail()
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

Issues with convolve
We obtained some disturbing results from convolve() (inaccuracies and negative probabilities). We'll try to make the context clear in as few lines as possible... Our function panjer() (code below) basically computes recursively the probability mass function of a compound Poisson distribution. When the Poisson parameter lambda is very large, the starting value of the recursive scheme ---

C function with unknown output length
Hi all, Could anyone point me to one or more examples in the R sources of a C function that is called without knowing in advance what will be the length (say) of the output vector? To make myself clearer, we have a C function that computes probabilities until their sum gets "close enough" to 1. Hence, the number of probabilities is not known in advance. I would like to have an

Out of bounds negative index
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

2.4.0 packages for (K)Ubuntu
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.

Dear R People: I have finally seen the error of my ways and have decided to use ESS for R and S + stuff. However, I have a question right from the beginning. I'm somewhat confused by the installation instructions. Do I install XEMACS or ESS first, please? Windows XP R Version 2.0.1 (S + 6.2) Thanks so much!
