[R] Automating package updates after major version change

[Sarah Goslee]

Hi Rich,

Note that install.packages requires "character vector of the names of
packages whose current versions should be downloaded from the
repositories" as stated in the help file.

If you aren't going to do it the way I did, then you need to read your
text file into R and create that character vector there.
