[R] Problem using package 'cgdsr' behind http proxy

[torbjoern.k at googlemail.com]

Dear R-users, -developers and -maintainers,

The situation is the following. My colleagues and me need to use the CGDSR-
package (http://www.cbioportal.org/cgx/cgds_r.jsp) on a Ubuntu 10.04 64bit 
workstation behind a HTTP proxy at campus. We 
are using R 2.12.2 (2011-02-25) retrieved via the Ubuntu-CRAN-repository.

Prior to starting R, the environment variable "HTTP_PROXY" is set via
	export HTTP_PROXY="username:password at server:port"

Within R
	Sys.getenv("HTTP_PROXY")
prints the correct variable.


After successful loading the cgdsr-library, a URL handler is set with
	mycgds=CGDS("http://cbio.mskcc.org/cgds-public/")
but when executing the test
	test(mycgds)
it returns an error stating, that it could not connect to the URL above on 
port 80. Thus I deduce, that the HTTP proxy settings are not used by the CGDSR 
package.

As I could not find a anything related to this problem in the CGDS 
documentation, I am posting here.
Is there any way of using a HTTP proxy with the CGDS package?

Thanks in advance for all your replies.

Kind regards
