#' Binary adjacency matrix for \code{neastdata}
#'
#' A matrix indicating the binary adjacency matrix for the
#' \code{neastdata}.  Some of the islands (e.g., Nantucket)
#' are considered adjacent to the mainland because of
#' ferries traveling from certain mainland regions to these
#' islands. Manual connections were added for many of the
#' New York counties because they are on islands. 
#' \code{neastw_old} is an old version included for backwards
#' compatibility.  \code{neastw_old} and has some
#' imperfections related to symmetry and does not have
#' as many connections for the New York counties.
