I have a table which has only numerical (actually integer) entries. Each row and column are indexed by a string. As an example,
I1L I1R I2L I2R I3 I4
—– —– —– —– —– —–
I1L 0 0 2 0 1 0
I1R 0 0 0 1 1 0
I2L 10 0 0 3 0 0
I want to be able to identify the non-zero entries and then create a 3-column table which has the row name, column name, and the integer value. For example,
I1L I2L 2
I1L I3 1
I1R I2R 1
I1R I3 1
I2L I1L 10
I2L I2R 3
Of course, the table that I am working with is quite large. I have been trying various combinations of commands, all in vain I'm afraid. I would very much appreciate any assistance. Thank you.
