How to set proxy in R ( ubuntu)

Question

Gaurav Pandey

I used the command

Sys.setenv(http_proxy="http://myusername:pswd@host:port")

and it worked at first. But on restarting It in the Terminal it showed the following error.-

 cannot open: HTTP status was '407 Proxy Authentication Required

How to resolve this issue.Help,,,

Answer 1

You set the environment for the process running R. When the instance of R exits, the process goes away, and the environment is gone.

You cannot set the environment for a parent process.

Put these commands in /etc/profile or ~/.bash_profile instead:

export http_proxy
http_proxy=http://myusername:pswd@host:port

Or all on one line (for bash ):

export http_proxy=http://myusername:pswd@host:port

Or run the commands in the shell before starting R .
