Antony, I am now utterly confused. The conditions involve column names of X1. In your first post I assumed you just meant "check for each row of x" not columns. After Arun replied I realized that may have been a wrong assumption, but I just don't understand how you get, for example the last TRUE (for the 90). Also, you failed to ?dput again. X2 is a matrix? of what ? expressions ? characters ? any way it looks like a list or a column vector to me. To avoid loops, David's suggestion could maybe be expanded to work with ?do.call if is.list(conditions), also see ?outer for matrices, but again I don't really understand what you're after. Sorry. Ilai
