Oops there was a bug... new.frame<-rbind(x.frame,y.frame); # A frame of the right size. new.frame[seq(1,nrow(new.frame),by=2),] <- x.frame # Assign every other row new.frame[seq(2,nrow(new.frame),by=2),] <- y.frame # Assign every other row.

I want to stack them piece-wise, not simply add one whole dataframe to the bottom of the other. I want to create as follows: x.frame: aX1 bX1 cX1 ... zX1 aX2 bX2 cX2 ... zX2 ... ... ... ... ... aX99 bX99 cX99 ... zX99 y.frame: aY1 bY1 cY1 ... zY1 aY2 bY2 cY2 ... zY2 ... ... ... ... ... aY99 bY99 cY99 ... zY99 new.frame: aX1 bX1 cX1 ... zX1 aY1 bY1 cY1 ... zY1 aX2 bX2 cX2 ... zX2 aY2 bY2 cY2 ... tY2 ... ... ... ... ... aX99 bX99 cX99 ... tX99 aY99 bY99 cY99 ... tY99 I have tried to use a for loop (simply assigning and also with rbind) to do this but am having difficulty correctly assigning the destination in the new dataframe. Can anyone offer a quick and easy way of doing this (or even a long winded one if it works!!)
