[R] Using older version of R

You can install both versions side by side, use the newer version and
xxxxxx package as needed, use the older version and your essential package
as needed, and shift results in .Rdata files -- or even as text files of
data -- between them as necessary.

This is obviously a nightmare and may be impossible for your needs, but it
is a problem of your own choosing.

Note: Please wait for other replies before trying this, as someone else may
have better ideas.
