Hi
I have the following problem
I would like to build, from a matrix filled with 0 and with 1, a matrix 
or a data.frame which contains, in every line, the number of the line 
and the number of the column of the matrix for which the value is equal 
to 1.
Exemple :

dput(m)
structure(c(0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 0, 1,
0, 0, 0, 1, 0, 0, 0, 0), .Dim = c(5L, 5L))

Result

1 5
2 3
2 4
4 1
4 3

Thank you for your help
