Is this the appropriate place for GSoC conversations? If I understand the proposal correctly, there should be a lexer (written in R) that exposes an API; that API would be used by segregated mini-parsers (Roclets) which do the dirty work of Roxygen -> {html, LaTeX, DocBook, ...} translation. The lexer should ship with a proof-of-concept Roclet. Have I missed anything?

Hi is there a list of all roxygen tags which are available? I couldn't find them. I am asking specifically towards the use of roxygen in documenting S4 classes - is that implemented yet (i am using roxygen 0.1 from CRAN at the moment)? Thanks Rainer -- Rainer M.

Is it possible to define an external special function (SPECIALSXP)? I'm trying to do some language-level work, and don't want my arguments evaluated before they hit C. It looks like the only way to define a SPECIALSXP is by using XX0 in the `eval' field of R_FunTab; is there any way to make this applicable to externally defined functions?

I'm trying to diagnose a bizarre problem in which the help files invoked from R are partially defective. help(), for instance, is missing the Description, Arguments and See Also sections; as are help files for other commands (see below). I've built 2.8.1, 2.10.1 and HEAD with the same results; do I need to set an environment or configuration variable? help

I understand why the following happens ($.proto delegates to get, which ascends the parent hierarchy up to globalenv()), but I still find it anti-intuitive: > z <- 1 > y <- proto(a=2) > y$z [1] 1 Although this is well-documented behavior; wouldn't it uphold the principle of least surprise to inherit instead from baseenv() or emptyenv()? (See attached patch.) Spurious

In principle, I'd like to be able to do something like this: sge.parLapply(seq(10), function(x) parLapply(seq(x), function(x) x^2)) In practice, however, I have to resort to acrobatics like this: sge.options(sge.remove.files=FALSE) sge.options(sge.qsub.options='-cwd -V') sge.parLapply(seq(10), function(x) { sge.options(sge.save.global=TRUE)

I was looking for an R-package that would reduce matrices to row-echelon form, but Google was not my friend; any leads? If not, I wonder if the problem could be expressed in terms of constraint satisfaction...

Hadley Wickham refactored roxygen, making it more maintainable and robust; the changes are so significant that we decided to nominate it roxygen2: http://cran.r-project.org/web/packages/roxygen2/index.html Some highlights: * it's faster; * usage has been improved (the @usage tag should be obsolete); * @rdname merges documentation for multiple functions into one file. For details,

We're pleased to announce that Henning Redestig finally implemented ESS support for Roxygen: http://www.metabolome.jp/download/ess-roxy/ess-roxy.el/view ess-roxy includes paragraph fill, hiding, template generation, etc.

I'm parallelizing some computation on hierarchical data, and would find it natural to do something like this (where a call to parLapply is embedded in outer call to parLapply): cl <- makeCluster(rep.int('localhost', 5), type='SOCK') clusterExport(cl, 'cl') parLapply(cl, 1:5, function(i) parLapply(cl, 1:5, function(j) i * j)) Snow

I successfully chrooted R running Rserve with an unprivileged user, and thought I'd publish the process. Attached is a jailkit.ini for use with jailkit;* and a chroot/setuid wrapper, chwrap.c. To set up the chroot in, for instance, /var/R; perform: mkdir -v /var/R jk_init -v -c jailkit.ini -j /var/R R then create the unprivileged user `r': useradd r After compiling chwrap
