Hi Networkers,


Just trying to take a large list of authors who have worked on papers and turn into network in R igraph.

So input looks like (simplified but can be any number of authors per paper):

Paper1, John, Mary, Sam

Paper 2, John, Roger, Trevor, Sue, Peter



I need to make it a pair wise list (or alternative for igraph input) for each row so looking like this:

John, Mary

John, Sam

Mary, Sam

John, Roger

John, Trevor

John, Sue

John, Peter

Roger, Trevor

Roger, sue

Roger, peter,

Trevor, sue

Trevor, peter

Sue, peter



Any suggestions welcomed.
