R 2.8.1, Firefox 3.0.11, windows XP Philippe, I suspect there are more substantial problems with the link to the WIKI then you thought. When I tried your code I got a page that contained nothing more than (excluding the nice graphic header and the index on the left-hand page):
Trace: » barplot == Rwiki file not found! == There is a helpful discussion of adding labels to barplots here: https://stat.ethz.ch/pipermail/r-help/2002-October/025879.html This WIKI page is not at all useful,it does not as you suggested it does not contain the help page of ?barplot in wiki format as you suggested int would!

If you try this in R on a computer that is connected to the Internet: wikihelp <- function(topic) browseURL(paste("http://wiki.r-project.org/rwiki/rhelp.php?id=", topic, sep = "")) wikihelp("barplot") You got the help page of ?barplot in wiki format (with a few presentation bugs, but everything is there, basically)... plus a Wiki discussion section where people can add more material, links, etc. The help page is not physically contained in the wiki page, but it is a file stored elsewhere on the R Wiki server, and that is supposed to be updated regularly (but it is not the case for the moment). In the wiki page you see, there is only a ~~RDOC~~ marker indicating where to include the help page. I have a problem with the R Wiki cache: until someone adds comments to such a page, the content is not refreshed, but you just see ~~RDOC~~. Try, for instance: wikihelp("chisq.test") If the engine thinks 'topic' is ambiguous, it displays a list of possibilities (i.e., our wikihelp() function is somehow a mix of help() and of apropos()). For instance: wikihelp("help") This should not be ambiguous, but it is considered as it currently by rhelp.php (a minor bug probably easy to correct). Finally, all wiki pages are spelled with lowercase. It is the same for help pages. So, wikihelp("RSiteSearch") wikihelp("rsitesearch") lead to the same rdoc:utils:rsitesearch wiki page. I have no solutions for that! So, to conclude, most of the required mechanism is already installed on R Wiki. It just needs a little bit of debugging and fine-tuning to become completely operational. A little help here would be very appreciated! ... and, of course, a refined version of the wikihelp() function must be made widely available to "reveal" this function. One could even consider to write a pager that displays local help page and warns if there are comments on this topic posted on the wiki... or that link to a personal wiki engine where everybody could add its own comments to the help pages, with full-text search ability!
