[R-wiki] rdoc pages not finding R docs?

[Philippe Grosjean]

Hello,

This bug is known, but I did not found a workaround yet. Basically, the 
RDoc plugin includes the content of the corresponding help file on top 
of the wiki page. Unfortunately, the cache mechanism of the wiki engine 
does not detects these additions. Consequently, the page looks empty 
until it is first edited (actual edition, the wiki engines always 
compare pages before and after edition before to decide if it is worth 
updating the cache version, but the RDoc content is invisible for it).

I though using the ~~NOCACHE~~ flag would solve the problem, but 
apparently not. The solution is probably to write a PHP program that 
flushes the cache for each of these RDoc pages and triggers the Wiki 
engine to calculate a new version of this cache. This should be part of 
a robot that automatically updates the Wiki R documentation according to 
new versions of R, or R packages, as scanned on CRAN periodically. It 
should be better a PHP program because the wiki engine itself is written 
in PHP.

This is planned for the future,... but I have no date, because I am 
really too busy right now (full-time prof + direction of an experimental 
lab, no technician, no assistant yet, thus, a crazy situation where all 
my remaining time besides teaching is dedicated to my Master and PhD 
students).

On the same line, the RDoc-to-wiki converter (Perl code, according to 
the code used by R to convert RDoc to man pages, HTML pages, LaTeX, ...) 
still have to be finished before it could be proposed as an addition to 
R. Help would be very welcome for both of these topics (finishing of the 
RDoc to Wiki converter in Perl, and robot in PHP to update Wiki help 
pages automatically). Any volunteer?

Best,

Philippe
