Problems are showing up with libgfortran3 and liblapack3.
Results of apt-cache policy are below. FYI no part of R is currently
installed on my system. Thanks.
root@bwud:/etc/apt# apt-get install r-base-core
...
The following packages have unmet dependencies:
r-base-core : Depends: libgfortran3 (>= 4.3) but it is not going to be
installed
Depends: liblapack3 but it is not going to be installed or
liblapack.so.3
Recommends: r-recommended but it is not going to be

+1
And that is what I was referring to with 'show us your error messages'. If
something 'blocks', do a 'apt-cache policy nameofthatpackage' to see where it
came from. Worst case, uninstall components (carefully) as suggested here.
By removing R and pieces you should not be able to brick your system.
PPAs are great, but they are /not/ tested against each other as the distro
core is.
