Hi Cristian,
I don't know about a R routine for exact CIs, but I found a function called
"ageadjust" using a gamma distribution approximation some time ago
-take a
look at http://medepi.org/epitools/rfunctions/index.html.
That Webpage seems a bit outdated now, but the calculations given in the
ageadjust functions should still work, I think.
Maybe this helps;
regards
Heinrich.
