[R] replacing a character string

[toehanus]

I am working on modifying a REDCap survey.  The data dictionary column for
the response field has the following value.

1, Strongly disagree | 2, Disagree | 3, Agree | 4, Strongly Agree | 5, Don't
Know | 6, Refuse to Answer | 7, Not Applicable

I am wanting to convert this so that it looks as follows:

1, A. Strongly disagree | 2, B. Disagree | 3, C. Agree | 4, D. Strongly
Agree | 5, E. Don't Know | 6, F. Refuse to Answer | 7, G. Not Applicable

Not all responses have these same values.  Some questions are Yes/No answers
and some have up to 13 different response options.  I have been trying to
use the sub function to do this, but with no real success.  I would
appreciate any help that you can give.  If you need more information, let me
know.  Thanks!

Thomas
