Hello, This is to announce the first release of the "ant" R package, which has been pushed to CRAN yesterday, and should reach your mirror and your platform soon. The package provides an R-aware version of the famous build tool from the apache project. http://ant.apache.org/ The package ships an R script that can be used to invoke ant with enough plumbing so that it can use R

Hello, I am using "R CMD INSTALL --clean" so that when my package is finished installed, a cleanup script is executed to post-process the generated html index file and add some more information. The cleanup (or cleanup.win script eventually calls the R code below) This works well, but it depends on the --clean switch. Is there another way, or can I force --clean (for example from

Hello, (This is a remix of this previous thread: https://stat.ethz.ch/pipermail/r-devel/2009-August/054264.html , but with a concrete example) I am developing some packages that contain scripts (for Rscript) and would like to know what is the best/recommended way to ship these scripts. An example is the "ant" package (R capable version of apache ant, see http://tr.im/xHLs). The

Hi, Would it be possible to add the capability for functions to register how they would like to complete themselves. Currently, there is the .addFunctionInfo, but it allows only functions to register a static list of potential completions, I was thinking of a way to register not a fixed list of possible completions, but a __function__ that would calculate completions dynamically. This could

Dear all Colleague of mine ask me if R is capable of Andrews plot like andrewsplot(x) in Matlab. Quick search did not reveal anything but before I start to write any routine I would like to ask this ingenious audience if there is any implementation of Andrews plots somewhere. I know about parallel coordinate plots in lattice (although I do not use them as I am not sure what the plot tells

Hello, WRE contains the following information about the "exec" subdirectory of a package : "Subdirectory exec could contain additional executables the package needs, typically scripts for interpreters such as the shell, Perl, or Tcl. This mechanism is currently used only by a very few packages, and still experimental." I think it would be useful to expand "very

Hello, I'm trying to get S4 dispatch on S3 "connection" objects. So I do : setOldClass( "connection" ) and then : setGeneric( "bling", function(object) standardGeneric( "bling" ) ) setMethod( "bling", "connection", function(object) cat( "gotcha ", as.integer(object), "\n" ) ) but I get : f <- file(

Hello, I very much enjoy "with" and "subset" semantics for data frames and was wondering if we could have something similar with split, basically by evaluating the second argument "with" the data frame : split.data.frame function(x, f, drop = FALSE, ...){ call <- match.call( ) fcall <- call( "with", data = call[["x"]],

Hello, Is it possible to have the effect of UserDefinedDatabase outside of "attached" environments ? Can I disguise an environment of the sys.frames() as a UserDefinedDatabase ? This seems to suggest that it might be possible : > f <- function(){ e <- environment(); class(e) <- "UserDefinedDatabase"; ff } > f() *** caught segfault *** address (nil),

Hello, I've been trying to make LinkingTo work when the package linked to has c++ code. I've put dumb packages to illustrate this emails here ; http://addictedtor.free.fr/misc/linkingto Package A defines this C++ class: class A { public: A() ; ~A() ; SEXP hello() ; } ; Package B has this function : SEXP say_hello(){ A a ; return a.hello() ; } headers of package A are copied

Hi all, When developing a package, it's often useful to be able to reload it, without re-installing, re-starting R and re-loading. To do this I've written a little script that inspects the package description and loads dependencies, data and code - http://gist.github.com/180883. It's obviously not very general (being tailored to my description files) and won't work for packages

Hello list, I use R for microarray analysis. One procedure I use takes a large matrix, and loops through it looking for specific rows, does an operation with them, and outputs a result (single row) as a row of another matrix. The loop goes on about 25000 times. When I run the loop directly from the R console itself, it takes about 3 minutes in my computer. I'm ok with that. Now,

Hello, Today, Brian Ripley commited the revision 50000 of R's svn repository.
