I have 5 values : chr [1:5] "A", "B", "C", "D", "E".

And one csv table and one column in this csv file is "Letter" which some Letter contains the above 5 values.

I wonder to create a Co-occurrence matrix to show the frequency amount of this 5 values mentioned in this csv file.

A	B
A	0
B	1

Thank you so much for your help!

Can you provide a small reproducible example? To me it's not clear what the question is exactly, but perhaps `table()` is what you're after? – Roman Luštrik Feb 15 '22 at 17:24
