Hi All,
I'm building a 9x9 grid like list, and I want to extract each column of
that grid.
My input is a list of integers as follows;
input = [0, 0, 0, 0, 0, 0, 4, 0, 9,
0, 0, 0, 0, 8, 0, 0, 5, 0,
7, 0, 2, 4, 5, 3, 6, 0, 0,
6, 7, 0, 0, 0, 1, 5, 0, 2,
2, 0, 8, 7, 0, 4, 3, 0, 1,
9, 0, 4, 5, 0, 0, 0, 8, 6,
0, 0, 6, 3, 1, 9, 8, 0, 7,
0, 2, 0, 0, 7, 0, 0, 0, 0,
1, 0, 7, 0, 0, 0, 0, 0, 0]
Try the function chunksOf of package split[0]
