You're right, I have tried keeping the double quotes in there too and that doesn't work
 
What is clear is that R is completely ignoring my http_proxy environment variable, as it's error says "unable to connect on port 80", when every single one of my http_proxy attempts has stipulates port 8080.... I know for a fact that my proxy isn't going to work on port 80.....
 
So what I need to know is why R is choosing to ignore http_proxy????

I'm not 100% sure but I think the double quotes are needed too. You've probably done this too.

	Hello Professor 

	If you are suggesting that I am simply missing the " http:// <http://> " part of my cache URL, or that I am missing a trailing "/", then I pre-empted this response and it still doesn't work.

	I have tried setting both http_proxy and HTTP_PROXY to all of: 

	wwwcache.bbsrc.ac.uk:8080 
http://wwwcache.bbsrc.ac.uk:8080 <http://wwwcache.bbsrc.ac.uk:8080>  
wwwcache.bbsrc.ac.uk:8080/ 
http://wwwcache.bbsrc.ac.uk:8080/ <http://wwwcache.bbsrc.ac.uk:8080/>  

	and I still get the same response - R cannot open the URL. 

	And yes, that is thw right proxy address, I copied it straight from Netscape on the same computer, and Netscape connects to the internet fine.

	Thanks 
Mick

	Your setting is wrong, so it is being ignored.  The help page says 
quite explicitly 

	      The form of `"http_proxy"' should be `" http://proxy.dom.com/ <http://proxy.dom.com/> "' or 
     `" http://proxy.dom.com:8080/ <http://proxy.dom.com:8080/> "' where the port defaults to `80' and 
     the trailing slash may be omitted.

	The problem is in your seeing, it seems.
