Hello,
I believe I don't understand your problem. Is this your input datum?
x <- "1, Strongly disagree | 2, Disagree | 3, Agree | 4, Strongly Agree
| 5, Don't Know | 6, Refuse to Answer | 7, Not Applicable"
If so the following will do it:
(search <- paste("(", 1:7, ",)", sep = ""))
(replace <- paste("\\1 ", LETTERS[1:7], ".", sep = ""))
xx <- x
for(i in 1:7)
xx <- gsub(search[i], replace[i], xx)
xx
If not, say so.
My doubt is in the input. Is the vertical bar a newline or row marker?
And the comma?
Hope this helps,
Rui Barradas

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
