[R] how to seperate a matrix
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 lot! My original matrix m is as follows for example, [,1] [,2] [,3] [1,]681 [2,]592 [3,]20 103 [4,]7 114 [5,]8 125 [6,]25 136 [7,] 14 147 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,]681 [2,]592 [3,]7 114 [4,]8 125 m2 supposed to be like: [,1] [,2] [,3] [1,]20 103 [2,]25 136 [3,] 14 147 How can I code the if statement?
