any other command that R uses to access the internet
Setting up a proxy in R 2.2.1 for windows.
I work at a Central Bank so our firewall and proxy are very particular. To
allow R to access the net I did the following:
1. In order for other programs, specifically STATA, to access the internet
we use a program called Privoxy. Download and setup Privoxy <
http://www.privoxy.org/> on your machine.
2. In IE (I'm using 6.0)
Tools > Internet Options > Connections tab > LAN Settings
Unselect both checkboxes in the "Automatic configuration" frame.
Select both checkboxes in "Proxy server" frame.
Address: localhost Port: 8118.
3. From the cmd prompt (Start > Run > Open:cmd) navigate to the folder
where you installed R. The default is cd C:\Program Files\R\R-2.2.1\bin.
At the prompt type:
C:\Program Files\R\R-2.2.1\bin>R - -internet2
This will start R calling internet2.dll and access the internet through IE
and with the IE settings you defined in step 2.
4. While I could not get the internet capabilities of R to work without
Privoxy, you may be more successful. If I were you I would begin by trying
to use your usual IE proxy and firewall settings without Privoxy and the
â- -internet2â option when starting R from the cmd prompt. I could not
figure out to how to invoke the internet2.dll flag using the GUI in
