The current version of R that is available in Wheezy is 2.15.1. However,
version 2.15.2 is available at CRAN sites. The site I use is
http://cran.case.edu/bin/linux/debian which states:
'If you want to have up to date R on wheezy I propose to directly
install Dirks packages from unstable (sid) by creating a file
/etc/apt/preferences containing
Package: *
Pin: release a=testing
Pin-Priority: 650
Package: *
Pin: release a=unstable
Pin-Priority: 600
and adding a line for unstable in /etc/apt/sources.list.'
I assume that the preference file should be in /etc/apt and not in
/etc/apt/preferences.d
My question is what should be the format of the line in the sources.lists?
Thanks in advance
