isnar: Introduction to Social Network Analysis with R

#' White's data on Effective Kinship Networks
#'
#' This data is taken from Freeman (1978) who uses data from White (1975) to
#' illustrate the segregation measure.
#'
#' Based on Freeman (1978):
#' 
#' White dealt with the problem of segregation among social positions rather
#' than among individual persons. He specified a set of standard kinship
#' positions that he called the ``effective kinship network''.
#' 
#' Traditional analysis (e.g. Murdock, 1971) have argued that societies
#' sometimes proscribe interaction among some kinship positions as an extension
#' of icest taboos.  Thus, given this reasoning, kinship positions should be
#' segregated according to the gender of their occupants. White's data provide
#' possibility to test of this hypothesis.
#' 
#' White collected data on the rules governing various kinds of interaction
#' among occupants of his ten standard kinship positions for a sample of 219
#' societies.  For every pair of positions White specified whether or not
#' interaction between their occupants was ever restricted in any society in
#' the sample.
