General plot add... functions

Description

General functions for adding extra layers to existing plots.

Usage

add.XYZGhosts(object = trellis.last.object(), 
              ..., unit = "native", 
              ghost.panel = panel.loaPlot) 

add.Y2Axis(object = trellis.last.object(), 
              ..., unit = "native", 
              rescale = NULL) 

add.XYPolygon(object = trellis.last.object(),
              x = NULL, y = NULL, data = NULL,
              ..., unit = "native",
              y2.scale=FALSE, first=FALSE)

add.LonLatMap(object = trellis.last.object(),
              ..., map = NULL, recolor.map=FALSE,
              show.axes = FALSE, unit = "native",
              first = TRUE)
                        

Arguments

object	The plot to add an extra plot layer or layers to. This defaults to last lattice plot produced if not set in call.
...	Additional arguments, passed on to related functions.
unit	The plot units, by default native.
ghost.panel	The plot panel to use when adding ghost points (lines, etc).
rescale	For add.Y2Axis, y data-series rescaling, by default NULL/none.
x, y	x and y data-series to be used.
data	If supplied, the expected source of x and y data-series.
y2.scale	When building the Plot, use the second y axis if that exists, default FALSE.
first	When building the plot add the new plot layer first, default varies.
map, recolor.map, show.axes	Options when adding a map layer, see loaMapPlot documentations.

Details

add.loaGhosts adds ghost points showing the locations of all points in all panels.

add.Y2Axis adds a second y axis.

add.XYPolygon adds a supplied (x,y) polygon.

add.LonLatMap adds a map layer.

Value

add... functions returns the supplied (or last) lattice plot with an additional plot layer added.

Note

add.XYZGhosts and add.LonLatMap are in-development and may change significantly in future package versions.
