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 [,1] [,2] [,3] [,4] [1,] 1 3 5 7 [2,] 2 4 6 8 Regards, Peng ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
