Marshall's infant mortality in Auckland dataset

Description

The 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, the "polylist" object auckpolys of polygon boundaries for the CAU, and a matrix of CAU bounding boxes auckbbs. The auckland data frame includes the following columns:

Usage

data(auckland)

Format

This data frame contains the following columns:

Easting
a numeric vector of x coordinates in an unknown spatial reference system
Northing
a numeric vector of y coordinates in an unknown spatial reference system
Deaths.1977.85
a numeric vector of counts of infant (under 5 years of age) deaths in Auckland, 1977-1985
Under.5.1981
a numeric vector of population under 5 years of age at the 1981 Census

Details

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.
