sr2css: Convert a Row-wise Self-Report Matrix to a CSS Matrix with Missing Observations
Description
Given a matrix in which the ith row corresponds to i's reported relations, sr2css creates a graph stack in which each element represents a CSS slice with missing observations.
A cognitive social structure (CSS) is an nxnxn array in which the ith matrix corresponds to the ith actor's perception of the entire network. Here, we take a conventional self-report data structure and put it in CSS format for routines (such as bbnam) which require this.
