R unable to access internet to install packages
a) You really should upgrade your version of R.
b) You have not indicated clearly what your operating system is as the Posting Guide requests of you (e.g. sessionInfo()), but if it is Windows then you should look at the R for Windows FAQ (section 2.19).

Hi,
I am having some trouble trying to install a number of packages in R on
my work computer. An example of the code I am using is as follows:
install.packages("ggplot2",dependencies=TRUE)
An example of the error messages I am getting is:
Warning: unable to access index for repository
http://cran.stat.auckland.ac.nz/bin/windows/contrib/2.9
Warning: unable to access index for repository
http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.9
Warning messages:
1: In open.connection(con, "r") : unable to resolve
'cran.r-project.org'
2: In getDependencies(pkgs, dependencies, available, lib) :
package ?ggplot2? is not available
The version of R I am using is 2.9.1.
I have tried the same script at home with no problems and also at my
previous workplace. I thought it may be to do with not having IT
administrator privileges but and IT administrator tried with the same
result and also tried the latest version of R with the same result. The
It administrator also did not see any internet traffic from my machine
when I tried the install so we have come to the conclusion that R must
not be able to access the internet from my machine ? I do have general
internet access.
We are using a proxy server (TMG ? Microsoft?s Threat Management
Gateway). Can R work with a proxy server on the network?
If so, how should this be configured so that a Network Administrator
can make the appropriate changes?
Thanks for your help.
Regards,
Alex Collier
