panel functions for spplot functions, and functions that can be useful within these panel functions
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, ...)
sp.grid(obj, col = 1, alpha = 1,...)
sp.text(loc, txt, ...)
| 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 forsp.linesof a
class that has a coordinates-methods forsp.points; of
class SpatialPolygons-class forsp.polygons.  When obj is
character, the actual object is retrieved byget(obj)before its
class is evaluated. | 
| 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 | 
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.
