panel and panel utility functions for spplot

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

Keywords
dplot
Usage
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.polygons(obj, col = 1, fill = "transparent", ...)
sp.grid(obj, col = 1, alpha = 1,...)
sp.text(loc, txt, ...)
Arguments
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
offset
offset for shifting a Polygons 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.polygonsplot for lines or 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.polygons and sp.text plot lines, points, polygons 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.
