## Elevation in Switzerland

### Description

Data required for plotting a Switzerland map with elevation.

### Usage

    data(swissalt)

### Format

This data set contains three R objects. 'alt.mat' is a 192 by 115 matrix giving the elevation at the grid points defined by 'lon.vec' and 'lat.vec'.

### Author(s)

Mathieu Ribatet

### Examples

    data(swissalt)

    layout(matrix(c(1,2), 1), width = c(3.5,1))
    mar <- rep(0, 4)
    op <- par(mar = mar)
    breaks <- seq(0, 2000, by = 250)
    image(lon.vec, lat.vec, alt.mat, col = terrain.colors(length(breaks) - 1),
          xaxt = "n", yaxt = "n", bty = "n", xlab = "", ylab = "", xlim =
    c(480, 840), ylim = c(58, 300))
    swiss(add = TRUE, city = TRUE)

    ##Heat bar
    mar <- c(3, 3, 3, 4)
    par(las = 1, mar = mar)

    plot.new()
    plot.window(xlim = c(0, 1), ylim = range(breaks), xaxs = "i",
                yaxs = "i")
    rect(0, breaks[-length(breaks)], 1, breaks[-1], col = terrain.colors(length(breaks) - 1),
         border = NA)
    axis(4, at = breaks[-length(breaks)])
    box()
    title("Elevation\n(meters)")
    par(op)
