geo (version 1.4-3)

gridaxes: Set up axes for a geoplot

Description

Set up axes for a geoplot.

Usage

gridaxes(limx, limy, scale, b0, xyratio, grid, col, reitur, smareitur, axratio, axlabels, b1, l1, projection, dlat, dlon)

Arguments

limx

Longitude limits

limy

Latitude limits

scale

Scale to supply to Proj, invProj

b0

Base latitude for the Mercator projection. Default value is 65 (typical for Iceland)

xyratio

Argument that can be used to set the aspect ratio (?)

grid

If grid is TRUE meridians and parallels are plotted, else not. Default TRUE

col

Color of gridlines

reitur

Should the grid show statistical rectangles?

smareitur

Should the grid show statistical sub--rectangles?

axratio

Parameter usually not changed by the user (?)

axlabels

If FALSE no numbers are plotted on the axes. Default TRUE

b1

Second latitude to define Lambert projection (?, as there's a Lambert version of this function)

l1

The longitude defining the Lambert projection, default is the l1 defined in geopar, ditto ??

projection

Projection ?, other than Mercator ??)

dlat

Latitude axis increment between labels

dlon

Longitude axis increment between labels

Value

No value, useful because of its side effect of adding axes to a geoplot.
