title: How Igraph handle weights?
body: <p>Good day to everyone.</p>
  
  <p>I have a really simple question that I wasn't able to find an answer, because of lack of terminology I am afraid. In r's package igraph how are considered weights? Are they considered a cost, therefore reducing the capacity of an edge or are they considered indeed as the capacity of the edge? </p>
  
  <p>Thank you very much</p>
