No. 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.
