Re turn values < 0 from Matrix
If your matrix is called mat, how about mat[which(mat[,2] > 0), ] mat[which(mat[,2] < 0), ] -Ian

Hi,
I have a matrix with negative and positiv values.
How can I get either the negative or positive values from the matrix?
Matrix:
[,1] [,2]
[1,] 1 -3
[2,] 2 -2
[3,] 3 5
[4,] 4 -2
[5,] 5 9
[6,] 6 8
[7,] 7 -2
What I want to have is:
[,1] [,2]
[1,] 1 -3
[2,] 2 -2
[3,] 4 -2
[4,] 7 -2
and:
[,1] [,2]
[1,] 3 5
[2,] 5 9
[3,] 6 8
Regards
