[R] microsoft proxy & R project

[Nolwenn LeMeur]

Hi Laurent,


You should look the R windows FAQ web page:

(a) Use the alternative |internet2.dll| by starting R with the flag 
--internet2 (see How do I install R for Windows? 
<http://cran.r-project.org/bin/windows/base/rw-FAQ.html#How-do-I-install-R-for-Windows_003f>) 
which uses the Internet Explorer internals (and so needs Internet 
Explorer 4 or later installed). Note that this does not work with 
proxies that need authentication.

(b) A proxy needs to be set up: see |?download.file|. Here are two 
versions of an example (a real one, but from a machine that is only 
available locally) of a command-line in a short cut:

     "path_to_R\bin\RGui.exe" http_proxy=http://user:pass@gannet:80/
     
     "path_to_R\bin\RGui.exe" http_proxy=http://gannet/ http_proxy_user=ask

The second version will prompt the user for the proxy username and 
password when HTTP downloads are first used.
