Both this and Liviu's original solution destroy the factor nature of 'Species' (which may not matter, of course). How about (.xb <- iris[ iris$Species=='zz', ]) .xb <- .xb[1, ] # this probably shouldn't work, but it does.
This one is an excellent solution, but yet another---what I call---quirky behaviour from R. Thanks all! Regards Liviu
