One other point. If you find you need to set a system or user environment
variable then microsoft has a free tool called setx.exe that you can find here:

You can do this from within R using system().

There is also a free program setenv.exe which is more powerful than setx.exe.
You mentioned that deleting http_proxy from your environment through the OS
would fix your problem. setenv.exe can both set and delete environment
variables and you can specify user, system, etc. See description and

Hi,
I am trying to use R at work and at home on the same computer. At work, I have
a proxy, and at home, I do not. I have, for work, a User environment variable
http_proxy which I set in the OS (Windows XP Pro). When I am at work, and I
try to retrieve data from the web with 'read.csv',
Note that Windows XP has 4 types of environment variables and I suspect
that the problem stems from not taking that into account:

You can have 4 different http_proxy environment variables and if you
set one type but try to unset a different type then that will have no
effect on the one you

OK, I think I get that... do you know which namespace the Sys.setenv()
function affects? Do you know if there are functions in R that can alter the

Use the R Sys.getenv() command to get the
