I am using:

  • Ubuntu 15.04
  • RStudio 0.99.486.
  • R 3.1.2
  • proxy network with authentication

The problem occurs when I open RStudio and try to install any package. Example:

install.packages("ggplot2")

I get the following error: 

Installing package into ‘/home/eisti/R/x86_64-pc-linux-gnu-library/3.1’
(as ‘lib’ is unspecified)
Warning in install.packages :
  package ‘ggplot2’ is not available (for R version 3.1.2)`

I tried to follow steps from official support and I've seen this question and bunch of other things on Internet, but nothing helps me. BTW everything works fine on Windows.

Any help will be highly appreciated. Merci.

I've found already the answer. Every time I launch RStudio, the first thing I have to do is executing the following command:

Sys.setenv(http_proxy="http://user:password@proxy.com:port/")

Then I can install packages.

  • you can also put the following into a file at ~/.Renviron: http_proxy="http://user:password@proxy.com:port/". This will set the environment variable for your proxy each time you start R. See ?Startup. – amc Jun 14 '16 at 14:31
