If you're talking about this graph:

http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=109

The source is indeed available, just click on one of the (R) or  
Firefox icons under the Requirements/source code section.

The link is:

http://addictedtor.free.fr/graphiques/sources/source_109.R

In fact, if you have the 'quantreg' package installed, you can just  
source it from R and see the graph live :-), ie:

R> source("http://addictedtor.free.fr/graphiques/sources/source_109.R")
