[R-wiki] graphics gallery in wiki?

[Philippe Grosjean]

OK, now the integration between the R Wiki and the R Graph Gallery is 
almost completelly done. Romain and myself have added this:

1) A link to a wiki page for each graph in the R Graph gallery

2) The Wiki page relating to a given graph in the R Graph Gallery are in 
the section 'graph_gallery:graphXX', where XX is the number of the graph 
in the gallery. The page displays the graph (with a link to the 
corresponding page when you click on it), a link to the R code to 
generate this graph and a "Wiki discussion" section where people can add 
comments, further code, examples, etc... (see for instance 
http://www.sciviews.org/_rgui/wiki/doku.php?id=graph_gallery:graph51)

3) The corresponding pages are only created when someone add comments in 
the Wiki. If a page does not exist yet, a click from the Graph Gallery 
on the 'wiki page' link shows a "this topic does not exist yet" page... 
and you can click "Create this page" to create it. It is created from a 
template with all the required code already introduced. The reasons for 
not creating these pages automatically: we have only pages with material 
in the index, and no need to synch with the R Graph Gallery database.

4) A specific Wiki plugin generates the HTML code for the image and the 
link. Its syntax is very simple: {{arg>RGraph}}, and it does the rest 
for you!

5) For linking to graphs in the R Graph Gallery from elsewhere in the 
Wiki, I have added "interwiki" shortcut. You just have to type 
[[rgg>XX]] (where XX is the number of the graph) and you got a link to 
that page with a nice little bargraph icon in front of it. This is the 
same for linking to R code corresponding to the graph: you use just 
[[rggcode>XX]]. You can see this in: 
http://www.sciviews.org/_rgui/wiki/doku.php?id=wiki:specialformat

Best,

Philippe Grosjean

P.S.: for further integration, we should just look at an harmonization 
of the CSS between the two sites... and also on the colors for the code 
syntax coloring.

P.S.2: I also added convenient interwiki shortcuts for packages on CRAN, 
with little package icons. Try for instance [[rp>abind]], 
[[rpindex>abind]] & [[rppdf>abind]] (see also in the wiki:specialformat 
page)
