Marshall's infant mortality in Auckland dataset
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:
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.
This data frame contains the following columns:
