Hello, Suppose I have a matrix a where a= sp1 sp2 sp3 sp4 sp5 sp6 site1 1 0 1 1 0 1 site2 1 0 1 1 0 1 site3 1 1 1 1 1 1 site4 0 1 1 1 0 1 site5 0 0 1 0 0 1 site6 0 0 1 0 1 0
And I want to pack that matrix so that the upper left corner contains most of the ones and the bottom right corner contains most of the zeros so that matrix b is b= sp3 sp6 sp4 sp1 sp2 sp5 site1 1 1 1 1 0 0 site2 1 1 1 1 0 0 site3 1 1 1 1 1 1 site4 1 1 1 0 1 0 site5 1 1 0 0 0 0 site6 1 0 0 0 0 1 Can any of you help me with some code to accomplish this? I have tried different forms of order and can't seem to figure it out. Basically I want to order the matrix by both the rows and columns. Thank you for your help.
