[R] Converting SAS Code

I will offer an opinion, with which others may fairly take issue.

If you are coming from SAS and wish to learn R, you should forget about SAS
entirely; it is ancient and convoluted. But more to the point, as others
have already suggested, you will only confuse and hamstring yourself trying
to convert the programming paradigms of one language into another. Better
to consider the **tasks** you wish to accomplish and learn how to approach
them in the new language. I would add that this especially includes
learning about R's varied data structures for which there is no cognate in
SAS I think (correction requested if I'm wrong about this).

If this is a one-off, just finding a local resource to do the job for you
might be the best approach.

Cheers,
Bert
