mapZones: Add Zones to a Map [deprecated]

Description

WARNING: This function will be removed soon; see oce-deprecated.

Usage

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

Arguments

longitude

either a logical 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

line 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

Use mapGrid instead of the present function.

Plot zones (lines of constant longitude) on a existing map.

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

See Also

A map must first have been created with mapPlot.

Other functions that will be removed soon: addColumn, ctdAddColumn, ctdUpdateHeader, mapMeridians
