Unable to install zoo package (R)

Question

I am trying to download the zoo package to work with time series using:

install.packages("zoo")

but I get the following message:

--- Please select a CRAN mirror for use in this session ---  
Warning: unable to access index for repository http://cran.cnr.Berkeley.edu/bin/windows/contrib/2.12 
Warning: unable to access index for repository http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.12  
Warning messages:  
1: In open.connection(con, "r") :
  unable to connect to 'cran.r-project.org' on port 80.  
2: In getDependencies(pkgs, dependencies, available, lib) :
  package ‘zoo’ is not available  

I tried several different mirrors and I keep getting the same error... Is zoo just not available in most mirrors or is something going wrong?

Answer 1

Please see FAQ 2.19. Or, alternatively, a quick search for "unable to connect to 'cran.r-project.org' on port 80" on rseek.org.

Reading the FAQ and doing a search for the error will usually help you resolve most issues.
