Installing an older version of R Statistical package.

I'm currently ruing R version 3.0.2 and would like to install R version 3.0.1.

Investigating slightly different results with some hardcore number crunching. I tried this:

• sudo apt-get install r-base=3.0.1-1precise0

But get this:

jnowacki@Ubuntu-Z800F:~$ sudo apt-get remove r-base

Use 'apt-get autoremove' to remove them.

Which I find odd as it clearly exists:
