create trellis plot for ST objects
stplot(obj, ...)

names that will be used in the strip; trimDates(obj) trims "-01" ending(s) from printed Dates
logical; if TRUE, time will increas from top to bottom; if FALSE, time will increase from bottom to top
values at which colours will change; see levelplot
number of levels the range of the attribute would be divided into
numeric; if larger than 0, the number of seconds between subsequent animated time steps (loop; press ctrl-C or Esc to stop)
plotting mode; if "xy", maps for time steps are plotted;
if "xt", a space-time plot is constructed (see argument scaleX,
but read details below); if "ts", multiple-locations time series
are plotted in a single plot, or in a separate panel for each
attribute; if "tp" single- or multi-attribute time series are
plotted in multiple panels, one panel per location.
integer: 0, 1 or 2; when mode is "xt", used to determine
whether the index of the spatial location is shown (0), the x coordinate (1)
or the y coordinate (2).
see the auto.key argument in xyplot
character; plot title, use NULL to omit title
character; see xyplot
scales drawing; see scales argument of xyplot
x-axis label
y-axis label
character; use 'l' for lines, 'p' for symbols, 'b' for both lines and symbols
logical; repeat the animation in an infinite loop?
numeric; if at is not specified,
expand the data range with this factor to cover all values
number of time intervals, equally spaced
time cuts in units of index(obj); this overrides number
list or NULL; see spplot
numeric, x range
numeric, y range
In non-animation and "xy" mode, stplot is a wrapper
around spplot, that automically plots each time stamp in
a panel. The returned value is is a lattice plot.
In "xt" mode, a space-time plot with space on the x-axis and time
on the y-axis is plotted. By default, the space ID is plotted on the
x-axis, as space can be anything (points, polygons, grid cells etc).
When scaleX is set to 1 or 2, the x- resp. y-coordinates
of the spatial locations, obtained by coordinates, is
used instead. Beware: when the x-coordinate is plotted, and for
each (x,t) element multiple y-coordinates are sent to the plot,
it is not clear which (x,y,t) value becomes the plotted value,
so slicing single y values is adviced -- no checking is done.
The returned value is is a lattice plot.
In animation mode (animate > 0), single maps are animated
in an endless loop, with animate seconds between each. No
proper value is returned: the loop needs to be interrupted by
the user.
