panel and panel utility functions for spplot

Description

panel functions for spplot functions, and functions that can be useful within these panel functions

Usage

sp.pagefn(n)
spplot.key(sp.layout, rows = 1, cols = 1)
SpatialPolygonsRescale(obj, offset, scale = 1, fill = "black", col = "black",
        plot.grid = TRUE, ...)
sp.lines(obj, col = 1, ...)
sp.points(obj, pch = 3, ...)
sp.polygon(obj, col = 1, ...)
sp.grid(obj, col = 1, alpha = 1,...)
sp.text(loc, txt, ...)

Arguments

n ignored
sp.layout list; see spplot for definition
rows integer; panel row(s) for which the layout should be drawn
cols integer; panel column(s) for which the layout should be drawn
obj object of class SpatialPolygons-class for SpatialPolygonsRescale; of class SpatialLines-class, Lines-class or Line-class for sp.lines of a class that has a coordinates-methods for sp.points; of class SpatialPolygons-class for sp.polygon. When obj is character, the actual object is retrieved by get(obj) before its class is evaluated.
offset offset for shifting a Rings object
scale scale for rescaling
fill fill color
col line color
plot.grid logical; plot through grid functions (TRUE), or through traditional graphics functions (FALSE)
pch plotting character
loc numeric vector of two elements
txt text to be plotted
alpha alpha (transparency) level
... arguments passed to the underlying lattice or grid functions

Note

The panel functions of spplot, panel.gridplot for grids, panel.pointsplot for points, or panel.ringsplot for lines or rings (polygons) can be called with arguments (x,y,...). Customizing spplot plots can be done by extending the panel function, or by supplying an sp.layout argument; see the documentation for spplot.

SpatialPolygonsRescale scales and shifts an object of class SpatialPolygons-class; this is useful e.g. for scale bars, or other layout items.

sp.lines, sp.points, sp.polygon and sp.text plot lines, points, rings or text in a panel.

spplot.key draws the sp.layout object at given rows/cols.

sp.pagefn can be passed as a page argument, and will call function spplot.key for the last panel drawn on a page.
