mapDevice: Creates a plot device set up for maps

In rworldmap: Mapping global data, vector and raster.

Description

Creates a plot device suited for rworldmap plotting functions.

Usage

mapDevice(
            device = "dev.new"
          , rows = 1
          , columns = 1
          , plotOrder="rows"
          , width = NULL
          , height = NULL
          , titleSpace = NULL
          , mai = c(0, 0, 0.2, 0)
          , mgp = c(0, 0, 0)
          , xaxs = "i"
          , yaxs = "i"
          , ...)

Arguments

device	Character string which controls the type of plot default. The default uses your standard plot device. Giving the name of a plotting device function will use that instead. e.g. "pdf", "png", etc.
rows	The number of rows. Default 1
columns	The number of columns. Default 1
plotOrder	Option of 'rows' or 'columns'. For multiple plots whether to plot in row or column order. However, note that addMapLegend can have the effect of reverting order to rows.
width	The width of a single plot. This includes the margins. If you do not specify both width and height, suitable values will be calculated
height	The height of a single plot. This includes the margins. If you do not specify both width and height, suitable values will be calculated
titleSpace	The height in inches of the gap at the plot.
mai	The margin sizes in inches. If titleSpace is given this overrides mai[3].
mgp	As per par(mgp) in the graphics package
xaxs	As per par(xaxs) in the graphics package
yaxs	As per par(yaxs) in the graphics package
...	Further arguments to the device function

Value

Used for the side effect of creating a plot device, and setting graphical parameters for the device.
