mapZones: Plot zones on an existing map [DEPRECATED]

Description

Plot zones (lines of constant longitude) on a existing map. DEPRECATED--will be removed by end Sept 2014

Usage

mapZones(longitude, polarCircle=0, lty='solid', lwd=0.5*par('lwd'), col='darkgray', ...)

Arguments

longitude

either a boolean indicating whether to draw a zonal grid, or a vector of longitudes at which to draw zones.

polarCircle

a number indicating the number of degrees of latitude extending from the poles, within which zones are not drawn.

lty

line type

lwd

line width

col

colour

...

optional arguments passed to lines.

Bugs

This should use approx to fill in multiple segments within the line, so that e.g. great circle lines will be curved.

Details

Zones that will not fit in the plotting space are ignored.

longitudelim=c(-80,10), latitudelim=c(0,120),
projection="orthographic", orientation=c(45,-100,0))
