Hi all, Basically I want to make a binary hit matrix.
For instance, if I have a file called 'pair.txt': set_a gene_1 set_a gene_2 set_a gene_3 set_b gene_3 set_b gene_4 set_b gene_5 set_c gene_1 set_c gene_3 And I want to convert it to a binary matrix as: Rows set_a set_b set_c gene_1 1 0 1 gene_2 1 0 0 gene_3 1 1 1 gene_4 0 1 0 gene_5 0 1 0 Can anyone suggest how to do this? Thank you!
