So you want to translate a dataset 

X  H
1  3
3  1
3  4
2  8
1  1
3  1
etc...

[download]

into

X\H 1  2  3  4  5  6  7  8 etc...
1   1  0  1  0  0  0  0  0
2   0  0  0  0  0  0  0  1
3   2  0  0  1  0  0  0  0
etc...

[download]

? Just like an Excel pivot table?

    I think it depends on whether your hooks and hangers and ties etc. have 'names', or whether you could reliably track the data by index alone. Could you post a small sample of the real data you're trying to manipulate?

    EDIT: Sorry hdb, was aiming for OP.

      Only the closets need names - these are the genes, the next to levels are the amino acid positions in each gene of length L (hangers), and the number of mutations at each amino acid position (number of ties on hanger ). I think for the last two index would be sufficient?
