[R] Problems with connection via proxy

[Peter Wohlmuth]

Hi all,

when I want to install packages calling

install.packages()

or Bioconductor with

source("http://bioconductor.org/biocLite.R")
biocLite()

I get the following error message

Error in file(file, "r", encoding = encoding) : unable to open connection
In addition: Warning message: cannot open file ''

I'm quite new to Ubuntu Linux but I think the problem might be that I connect to the network via a proxy.

Do you agree?
I set the enviromental variable with export "http://www.univie.ac.at/proxy" and tested it

> Sys.getenv("http_proxy")
                     http_proxy 
"http://www.univie.ac.at/proxy" 

but the error message still occured.

Do you have an idea how I can solve the problem and save the setting in the Startup permanently?

Thank you and kind regards
