Hi,
Suppose I have the following two matrices.
x=matrix(1:4,nr=2)
y=matrix(5:8,nr=2)
I want to join the two matrices to get the following two new matrices.
I did a search but I don't find any relevant webpage. Can somebody let
me know how to do it?
[,1] [,2]
[1,] 1 3
[2,] 2 4
[3,] 5 7
[4,] 6 8
?rbind
[,1] [,2] [,3] [,4]
[1,] 1 3 5 7
[2,] 2 4 6 8
?cbind
These are pretty basic questions. What introductory documents are you
working with that don't describe rbind and cbind at an early stage of
matrix operations?
