\description{
(Use \code{example(auckland)} to load the data from shapefile and generate neighbour list on the fly).  The \code{auckland} data frame has 167 rows (census area units --- CAU) and 4 columns. The dataset also includes the "nb" object \code{auckland.nb} of neighbour relations based on contiguity, and the "polylist" object \code{auckpolys} of polygon boundaries for the CAU. The \code{auckland} data frame includes the following columns:
}
\details{
The contiguous neighbours object does not completely replicate results in the sources, and was reconstructed from \code{auckpolys}; examination of figures in the sources suggests that there are differences in detail, although probably not in substance.
