world: Plot of the world

Description

Plots quickly, medium resolution outlines of large land masses and bodies of water.

Usage

world(ylim=c(-90, 90), xlim=c(-180, 180), add=FALSE, asp = 1,
      xlab = "", ylab = "",  xaxt = "n", yaxt = "n", ...)

Arguments

ylim

range of latitudes

xlim

range of longitudes

add

logical; if true will add the world map to current plot.

asp

aspect ratio used if add is false, see plot.default.

xlab,ylab

labels for x- and y-axis; empty by default.

xaxt,yaxt

axis type for x- and y-axis; empty by default.

...

These are graphical arguments that are passed to the lines (and plot if add is false) function that draws the outline.

Details

This function uses the FIELDS dataset world.dat for the coordinates. The main advantage of this function is that it is fast and easy to modify.

Examples

# Draw map in device color number 2 ( usually red?) 

world( col=2)

## Western Europe (*which* big island is missing ?)
## with a (light color!) coordinate grid:

world(xlim=c(-10,18),ylim=c(36,60), xaxt = "s", yaxt = "s")
grid()
