Hello,
I am working on seperate the matrix to two matrices but got trouble on doing
it. Please give me some suggestions on doing this. Thanks a looooooooooooot!
My original matrix m is as follows for example,
[,1] [,2] [,3]
[1,] 6 8 1
[2,] 5 9 2
[3,] 20 10 3
[4,] 7 11 4
[5,] 8 12 5
[6,] 25 13 6
[7,] 14 14 7
I want to generate two matrix m1 and m2
if m[i, 1] <m[i,2], then the row is stored in new matrix m1, (i =1, ..., 7)
if m[i,1]>=m[i,2], then the row is stored in new matrix m2.
m1 supposed to be like:
[,1] [,2] [,3]
[1,] 6 8 1
[2,] 5 9 2
[3,] 7 11 4
[4,] 8 12 5
m2 supposed to be like:
[,1] [,2] [,3]
[1,] 20 10 3
[2,] 25 13 6
[3,] 14 14 7
How can I code the if statement? Thank you very much
