Configuring R to Use an HTTP or HTTPS Proxy

To set the required environment variables you should add them to the R environment file (which is read by R at startup). On RStudio Server this file is found at R_HOME/etc/Renviron.site. On RStudio Desktop this file is found in the user home directory at ~/.Renviron. You can easily access your .Renviron file by running the command file.edit('~/.Renviron') within RStudio

Note that these files might not exist in the default installation of R so you may need to create them if they aren’t already present.

http_proxy=http://proxy.dom.com/
http_proxy_user=user:passwd

https_proxy=https://proxy.dom.com/
https_proxy_user=user:passwd

how to change the default working directory

1. Navigate to ‘Rprofile.site’, open it in text-editor.
2. insert right at the top of the file in the first line the following command which tells R to set the working directory at start-up to the PATH you are specifying within the brackets (be sure you use double backslashes “” for Windows!)

   setwd("xxxx:\xxxx\xxxx")
