## Road Distances

### Description

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

### Usage

    data(capitales)

### Format

`capitales` is a list with the following components:

xy

  a data frame containing the coordinates of capitals

area

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

logo

  a list of pixmap objects, each one symbolizing a capital

Spatial

  an object of the class `SpatialPolygons` of `sp`, containing the map

dist

  a dist object the road distances between 15 European capitals

### Examples

    data(capitales)
    attr(capitales$dist, "Labels")
    index <- pmatch(tolower(attr(capitales$dist, "Labels")), names(capitales$logo))
    w1 <- capitales$area

          plot = FALSE)
        g2 <- s.logo(capitales$xy[sort(rownames(capitales$xy)), ], capitales$logo,
          Sp = capitales$Spatial, pbackground.col = "lightblue", pSp.col = "white", pgrid.draw = FALSE,
          plot = FALSE)
