[R-wiki] Beginner - Intermediate - Advanced indicator

[Philippe Grosjean]

Hello,

Although the R Wiki site would primarily be dedicated to beginners, 
there is already, and there will be in the future several pages dealing 
with more advanced topics.

In order to spot this, I propose little icons easy to integrate in the 
pages (for instance :--+: means something dedicated exclusively to 
experts, see: "Smileys & other icons in 
http://www.sciviews.org/_rgui/wiki/doku.php?id=wiki:syntax).

You can see examples of using these indicators at:
http://www.sciviews.org/_rgui/wiki/doku.php?id=rtips:data:import
and 
http://www.sciviews.org/_rgui/wiki/doku.php?id=beginners:surprises:emptysetfuncs
for instance.

What do you think about it? Personnally, I found them nice when I did 
draw the icons, but they look a little "toyish" once integrated in the 
Wiki pages. Does someone have a better idea to help spotting items 
related to each user's skill?

Best,

Philippe Grosjean
