Road Distances

Description

This data set gives the road distances between 15 European capitals and their coordinates.

Usage

data(capitales)

Format

This list contains the following objects:

dist

is dist object the road distances between 15 European capitals.

xy

is a data frame containing the coordinates of capitals.

area

is a data frame containing three variables, designed to be used in area.plot function.

logo

is a list of pixmap objects, each one symbolizing a capital

Spatial

is a SpatialPolygons object containing the map
