RStudio Proxy Configuration on Windows

Question

This question has been asked in: Configure proxy on Rstudio. However, it was never resolved.

I am a user of RStudio 0.99.486 version and R 3.2.2 version. I have tried 2 ways to configure proxy settings in the office without success after reading several suggestions:

FIRST TRY: Type in Rstudio as first line: Sys.setenv(http_proxy="http://user_name:[email protected]_domain.es:8080/")

Go to: -Tools, -Global Options, -Packages, and unmark option:

"Use internet library/proxy for HTTP"

I also unmarked the option: "Use secure download method for HTTP".

Besides, I right-clicked on the R x64 3.2.2 icon of the desktop and added after 1 space in the "Target" camp:

http_proxy=http://user_name:[email protected]_domain.es:8080/

It did not work as I received the message:

Warning in install.packages : cannot open: HTTP status was '407 Proxy Authentication Required'

SECOND TRY: Create a notepad file with the name:

.Renviron

Saved it in: "C:\Users\username\Documents".

The file contains inside the following 2 lines:

http_proxy=http://proxy.company_domain.es/
http_proxy_user=user_name:password

When I try installing a package I receive:

"Warning in install.packages : unable to connect to 'cran.rstudio.com' on port 80. Unable to access index for repository http://cran.rstudio.com/src/contrib"

After running code line: R.home() My R_HOME route is:

"C:/Program Files/R/R-32~1.2"

I appreciate before-hand for your advice and help.

Answer 1

Thank you for your question. It helped me to resolve my issue. I had to unmark the option to use the settings from the Internet Explorer and restart.

Maybe your .Renviron does not contain the proxy port, you have to write

http_proxy=http://proxy.company_domain.es:8080/
http_proxy_user=user_name:password

If you specify

http_proxy_user=ask

it should prompt you for user name and password - then you know that the file is read

Answer 2

I also nearly gave up on this problem until I found this simple solution (R3.3.1):

1. specify the system environment variables (in Windows Advanced System Settings add the variables http_proxy and https_proxy and set it to http://user_name:[email protected]_domain.es:8080/ with your specific settings)

2. in the R console type

update.packages(ask='graphics',method="libcurl",checkBuilt=TRUE)
