Hi all,

Following previous threads I have installed and using a 2.7.0 beta release:

 > version
               _                                      
platform       i386-apple-darwin8.10.1                
arch           i386                                   
os             darwin8.10.1                           
system         i386, darwin8.10.1                     
status         beta                                   
major          2                                      
minor          7.0                                    
year           2008                                   
month          04                                     
day            10                                     
svn rev        45232                                  
language       R                                      
version.string R version 2.7.0 beta (2008-04-10 r45232)
 >

When trying to install any package I get the error:

Warning: unable to access index for repository 
http://r.research.att.com/bin/macosx/universal/contrib/2.7

Please, what repository must I use? I guess the command must be

 > options(repos=c(CRAN="repository URL"))

Thanks for your help!

Ricardo
