That being so, it seems you need to accumulate row names by hand, as you
guessed.
forval i = 1/15 {
local names `names' `=tapm[`i']'
}
matrix rownames R = `names'

Thanks Nick, but that option must be new in Stata 10.
Stata 9 has a -matname- command and also -matrix rownames-,
but both need an explicit <namelist>, not a variable name.
Ah well, one more reason to upgrade.
