Re: [R] question about rev

the function /rev / REVERSEs the order of the vector, as v= c(1,2,3) rev(v)= 3,2,1 if you want the opposite value , just add a exclamation in front of the vector: v=c(T,F,T,T); !v is F,T,F,F -- View this message in context: http://r.789695.n4.nabble.com/question-about-rev-tp4268518p4268716.html
