Description

This data set gives the road distances between 13 towns in New-Zealand.

Usage

`data(zealand)`

Format

`zealand` is a list with the following components:

a data frame with 13 rows (New Zealand towns) and 13 columns (New Zealand towns) containing the road distances between these towns

xy

a data frame containing the coordinates of the 13 towns

neig

an object of class `neig`, a neighbour graph to visualize the map shape

nb

a neighborhood object (class `nb` defined in package `spdep`)

Examples

```data(zealand)

psub.text = "Distance canonique", plot = FALSE)
g2 <- s.label(cmdscale(d0), lab = as.character(1:13), nb = zealand\$nb,
psub.text = "Distance routiere", plot = FALSE)
g3 <- s.label(cmdscale(d1), lab = as.character(1:13), nb = zealand\$nb,
psub.text = "Distance routiere / Cailliez", plot = FALSE)
