example(auckland) to load the data from shapefile and generate neighbour list on the fly).
auckland data frame has 167 rows (census area units — CAU) and 4 columns. The dataset also includes the "nb" object
auckland.nb of neighbour relations based on contiguity, and the "polylist" object
auckpolys of polygon boundaries for the CAU. The
auckland data frame includes the following columns:
This data frame contains the following columns:
a numeric vector of x coordinates in an unknown spatial reference system
a numeric vector of y coordinates in an unknown spatial reference system
a numeric vector of counts of infant (under 5 years of age) deaths in Auckland, 1977-1985
a numeric vector of population under 5 years of age at the 1981 Census
The contiguous neighbours object does not completely replicate results in the sources, and was reconstructed from
auckpolys; examination of figures in the sources suggests that there are differences in detail, although probably not in substance.
