Error when trying to upload a package in R Project

[walkerhound]

When I try to upload a package into R Project (from the packages tab) I get an error:

Cannot install package 'igraph'. Attempt to download CRAN description from 'http://cran.r-project.org/web/packages/igraph/DESCRIPTION': [Errno 11004] getaddrinfo failed

I have tried a few packages. The URL http://cran.r-project.org/web/packages/igraph/DESCRIPTION seems okay.

I suspect this is a proxy issue but I'm not sure how to fix it.

Hi walkerhound,

this could be related to a proxy issue. If you must use a proxy server to get to the internet, set the http[s]_proxy user env for the user running Splunk like this for Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com

For Linux:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com 

But the error code you get could also point to some trouble resolving the hostname, so check your DNS as well.

cheers, MuS

I got it to work. I had to put in the username and password for the proxy.

Thanks.

I have added the proxy with username and password and still can't get this solution to work. Any other ideas?
