I've regained access to this issue. In facts, it has never been solved! 
My old message with a solved in it talked about my error sending HTML 
formated messages, not about how to deal with this issue. Sorry for not 
being clear!

I invested a lot of time looking for a solution but every alternative 
fails at one end: XWiki doesn't accept username:password pairs in the 
URL yet and I don't know how to pass these parameters to the 
download.file R function.

What keeps been truth is that this, for instance, works at command line 
(in my case, MacOSX terminal):

wget --http-user=DummyDummy --http-password=dummy --auth-no-challenge 
--output-document=RG2.txt 
http://xepecnet.environmentalchange.net/xwiki/bin/view/ICT/RGraphicSample02?xpage=plain

And saves RG2.txt in your current directory. But I don't now yet how to 
pass parameters like --http-user to method wget in R download.file.

Perhaps you could try this syntax to see if Google accept it.

OK, wget is not in R, but it could be used within R download.file 
function, so I would think that this is a possible place to ask about 
this topic. Thanks!!!

Greetings,

Ricardo
