it's clear, he wants to combine x and y s that the result is (x[1], y[1], x[2], y[2], ...), unless i am confused as well ;)
now, both rbind(x,y)[1:length(x)] and as.vector(mapply(c,x,y)) do the job, but the former is *much* faster: t1 = function(n) as.vector(mapply(c, 1:n, 1:n)) t2 = function(n) rbind(1:n,1:n)[1:(2*n)] system.time(t1(10^6)) # ~7sec system.time(t2(10^6)) # < 1sec system.time(replicate(10^5, t1(10))) # ~20sec system.time(replicate(10^5, t2(10))) # ~1sec vQ Doran, Harold wrote: > Shubba > > I'm confused.
