Let's say I have some IDs 1,3 and 5, how would I create data frame (or matrix) which has those ID's as column/row names, so looking like this:
IDs
IDS 1 3 5
1 NA NA NA
3 NA NA NA
5 NA NA NA
Just a note, those IDs could be any large number, I just took that as example. Here below is another example, what I'm aiming that. I found this example of data but it was already in .rdata format so I have no clue how to re-create it.
