Thank all help help. Ted's intuitive single step definition is what I want. I try to teach elementary Linear Algebra using R to manupilate matrices. Since my students have no programming experience at all, any fancy and muliple step definition in matrix row operation will confuse them. Again, I appreciate the suggestions from all of you! -- View this message in context: http://r.789695.n4.nabble.com/How-to-define-new-matrix-based-on-an-elementary-row-operation-in-a-single-step-tp2341768p2362791.html Sent from the R help mailing list archive at Nabble.com.
