mapAxis: Plot axis labels on an existing map

Description

Plot axis labels on an existing map

Usage

mapAxis(side=1:2, longitude, latitude,
        tick=TRUE, line=NA, pos=NA, outer=FALSE, font=NA,
        lty="solid", lwd=1, lwd.ticks=lwd, col=NULL, col.ticks=NULL,
        hadj=NA, padj=NA, tcl=-0.3, debug=getOption("oceDebug"))

Arguments

side

the side at which labels are to be drawn. If not provided, sides 1 and 2 will be used (i.e. bottom and left-hand sides).

longitude

vector of longitudes to indicate. If not provided, and if a grid has already been drawn, then the labels will be at the interesections of the grid lines with the plotting box.

latitude

vector of latitudes to indicate. If not provided, and if a grid has already been drawn, then the labels will be at the interesections of the grid lines with the plotting box.

tick

an argument that is transmitted to code{ink{axis}}.

line

an argument that is transmitted to code{ink{axis}}.

pos

an argument that is transmitted to code{ink{axis}}.

outer

an argument that is transmitted to code{ink{axis}}.

font

an argument that is transmitted to code{ink{axis}}.

lty

an argument that is transmitted to code{ink{axis}}.

lwd

an argument that is transmitted to code{ink{axis}}.

lwd.ticks

an argument that is transmitted to code{ink{axis}}.

col

an argument that is transmitted to code{ink{axis}}.

col.ticks

an argument that is transmitted to code{ink{axis}}.

hadj

an argument that is transmitted to code{ink{axis}}.

padj

an argument that is transmitted to code{ink{axis}}.

tcl

an argument that is transmitted to code{ink{axis}}.

debug

a flag that turns on debugging. Set to 1 to get a moderate amount of debugging information, or to 2 to get more.

Details

This function is still in development, and the argument list as well as the action taken are both subject to change, hence the brevity of this help page.

Note that if a grid line crosses the axis twice, only one label will be drawn.

Examples

library(oce)
data(coastlineWorld)
par(mar=c(2, 2, 3, 1))
lonlim <- c(-180, 180)
latlim <- c(60, 120)
mapPlot(coastlineWorld, projection="+proj=stere +lat_0=90",
        longitudelim=lonlim, latitudelim=latlim,
        grid=FALSE)
mapGrid(15, 15, polarCircle=1/2)
