Mac OS X 10.4.11 - R2.6.2 - Problem with proxy

Hello,

    I have 60 Macintoshs on Mac OS X 10.4.11 for learn "R" to studient 
of University and i want to Install New Packages. I click on the button 
"access list Mirrors" and it propose me a list of mirrors. None work 
correctly. All the mirrors take an error. For exemple for the Lyon 
(France) Mirror, it write :
 > trying URL 'http://cran.univ-lyon1.fr/bin/macosx/2.1/PACKAGES'
 > Error in download.file(url = paste(contriburl, "PACKAGES", sep = 
"/"),  :
 >    cannot open URL 'http://cran.univ-lyon1.fr/bin/macosx/2.1/PACKAGES'
 > In addition: Warning messages:
 > 1: unable to load shared library 
'/Library/Frameworks/R.framework/Resources/modules/R_X11.so':
 >  dlcompat: dyld: /Applications/R.app/Contents/MacOS/R can't open 
library: /usr/X11R6/lib/libSM.6.dylib  (No such file or directory, errno 
= 2)
 > 2: unable to connect to 'cran.univ-lyon1.fr' on port 80.

I'm of course Administrator on the computer for try to install packages.

We use a proxy inside the University who is configure on the g?n?ral 
pr?f?rences on Network of the Macintosh. No problem for come on internet 
with help of math?matica for example or others Internet Browser.

I can't imagine install 20 ou 30 packages by hand on all the Macintosh. 
And i want the studient learn hows it's easy to use "R". So i hope you 
can help me ...

Thanks for all.
Bye
Vincent

Hello Vincent,

Recent versions of R have introduced some bug related to accessing the
Internet through a transparent proxy. It has been discussed recently,
twice, for the Windows and Linux platforms. Please check these threads
[1] [2].

Basically, you would need to install wget, make sure that it can
access the Internet (tweak the config files and make it aware of the
transparent proxy) and use method="wget" when installing packages
within R.
