mapAxis {oce} | R Documentation

## 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 codeinkaxis.
`line` | an argument that is transmitted to codeinkaxis.
`pos` | an argument that is transmitted to codeinkaxis.
`outer` | an argument that is transmitted to codeinkaxis.
`font` | an argument that is transmitted to codeinkaxis.
`lty` | an argument that is transmitted to codeinkaxis.
`lwd` | an argument that is transmitted to codeinkaxis.
`lwd.ticks` | an argument that is transmitted to codeinkaxis.
`col` | an argument that is transmitted to codeinkaxis.
`col.ticks` | an argument that is transmitted to codeinkaxis.
`hadj` | an argument that is transmitted to codeinkaxis.
`padj` | an argument that is transmitted to codeinkaxis.
`tcl` | an argument that is transmitted to codeinkaxis.
`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.

    ## Not run:
    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)
    mapAxis()
