This list is about general help for coding in R. I see no indication
of that in your query, which appears to concern statistical
methodology. In any case, R has a meta-analysis SIG that would seem
to fit your query better:

multiple choices (usually between 3 and 4). However, the reference isnt always
the same, so we could have study A who present results with A/B/C/D categories
with ?A? as reference, but study B who presents results with the same A/B/C/D
categories but with B as the reference. In the case of a dichotomous variable
and an odds ratio, we could ensure a common denominator among the study using
1/OR. Is there any reliable way to do so with a categorical variable (with OR
mostly, and possibly relative risks [RR])?
