Yes, there is the "interwiki" feature that rewrites links like 
[[wp>wiki]] to link to Wikipedia, topic "wiki". I'll see how I can add 
something to link to graphs and code.

By the way, for the code in the R graph gallery, I suggest you use the 
same modified GeSHi engine with R syntax highlighting that I am 
designing for the Wiki. It provides links to R functions man pages and 
nice syntax coloring of code. It is a PHP script. So, easy to integrate.

Currently, I am fighting with it to allow a better formatting of code 
(for instance, do not colorize arguments names similar to function 
names, as if they were functions, like in: x <- matrix(1:9, nrow = 3), 
where 'nrow' should not be colorized as a function, although the 
'nrow()' function exists in a different context).

I'll send you the customized GeSHi engine as soon as I will finish this 
fine-tuning.

Take care that the final URL will be different from 
http://www.sciviews.org/_rgui/wiki. I will dedicate a server for the R 
wiki at my University. Also, it is most probable that we end up with 
something like http://wiki.r-project.org, or http://www.r-project.org/wiki.

For the location of the pages, I suggest something like: 
graph_gallery:graph25. 'rgg' is not informative enough. So the 
*temporary* link should be:
http://www.sciviews.org/_rgui/wiki/doku.php?id=graph_gallery:graph25

The simplest way is to let create a page from this link (you first have 
a message that the page does not exists, suggesting you to create it). 
Then, I could add a template with a default title, a common text and the 
link to both the graph and the corresponding code (once the "interwiki" 
feature will be added) in that template.

I really think it is the best solution: we continue to use your 
excellent graph gallery engine, and we allow users to puts comments in 
the best place for that: the R wiki.
