All other answers I find only end up pointing to instructions: http://cran.r-project.org/bin/linux/ubuntu/
So interpreting that site, added line:
deb http://r.meteo.uni.wroc.pl/bin/linux/ubuntu oneiric universe
to /etc/apt/sources.list and ran apt-get update
.
(From experimentation I had to add the "universe" or "main" at the end to avoid parse error in the repositories list, preventing apt or synaptic from updating at all).
However the problem persists:
W: Failed to fetch http://r.meteo.uni.wroc.pl/bin/linux/ubuntu/dists/oneiric/main/binary-i386/Packages 404 Not Found
I enter that URL in a browser and clearly see that path is not there. However this is: http://r.meteo.uni.wroc.pl/bin/linux/ubuntu/oneiric/ (under which the Packages file actually lies, etc.)
Tried other mirrors, same problem.
lsb_release -a
Ubuntu 11.10
The version of R available initially prevents me from installing updated packages, eg.:
> install.packages("PerformanceAnalytics")
Installing package(s) into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
package ‘PerformanceAnalytics’ is not available (for R version 2.13.1)
Where I am going wrong?
