Hadley Wickham refactored roxygen, making it more maintainable and
robust; the changes are so significant that we decided to nominate it

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):

clusterExport(cl, 'cl')

A flat representation of our nested data is, alas, too large to

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(se

Ah; indeed, that /is/ the problem. Works fine from MinGW. If I have
some time, maybe I can investigate and submit a patch.

It is.

Interestingly, the html seems to be whole; but it's less convenient to
access from ESS, though.
Do you know what program generates the plain text; and are there any
options that govern where R looks
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

Good call; the vignette is terse and outdated. Manuel and I are in the

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

That's great, ronggui; looks like they do some things I tried on an
ad-hoc basis:
* site:r-project.org
* filetype:r
* etc.
but save a lot of typing. Thanks.

Adding `site:r-project.org' (no quotes) will get you official docs,
`site:stat.ethz.ch' will get the mailing lists; for instance:

Like the Law of Fives, it depends very much on the ingenuity of the

My undestanding is that assign applies to the parental environment;
but the return value of assign, namely 10, is passed to f as the local
variable a.

I never thanked you, by the way, John; have you considered incurring
the overhead of producing a formal R package?
Otherwise, it's worth its SLOC in gold.
