like not a question that belongs here. It actually is possible to run

Dear Erik,
There may be more elegant solutions, but try this:
a. Create a data frame with your data, for example
data - data.frame(agegrp, y1994, y1995, y1996)
b. Then use the which function:
as.character(aa$agegrp[which(aa$y1994==23)])

The main issue is that the original distributions are the same, you shift the
two samples *by different amounts* (about 0.01 SD), and you have a large
