I want to create?columns from this row vector. From: ??? x1 x2 x3 x1 x2 x3 x1 x2 x3 ???? 1? 2 3??1? 2??3??1?? 2? 3 to: x1 x2 x3 1? 2?? 3 1? 2?? 3 1? 2?? 3?Peter Maclean Department of Economics UDSM
You mean like:> myvec <- c(1,2,3,1,2,3,1,2,3) > myvec[1] 1 2 3 1 2 3 1 2 3> matrix(myvec, ncol=3, byrow=TRUE)[,1] [,2] [,3] [1,] 1 2 3 [2,] 1 2 3 [3,] 1 2 3>Or do you actually have more complex requirements?
