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
Peter Wohlmuth
