Road Distances
This data set gives the road distances between 15 European capitals and their coordinates.
data(capitales)
capitales is a list with the following components:
a data frame containing the coordinates of capitals
a data frame containing three variables, designed to be used in area.plot function
a list of pixmap objects, each one symbolizing a capital
an object of the class SpatialPolygons of sp,
containing the map
a dist object the road distances between 15 European capitals
