produce trellis plot for STxDF object
create trellis plot for ST objects

obj |
object of a class deriving from |
names.attr |
names that will be used in the strip; trimDates(obj) trims "-01" ending(s) from printed Dates |
as.table |
logical; if TRUE, time will increas from top to bottom; if FALSE, time will increase from bottom to top |
at |
values at which colours will change; see levelplot |
cuts |
number of levels the range of the attribute would be divided into |
animate |
numeric; if larger than 0, the number of seconds between subsequent animated time steps (loop; press ctrl-C or Esc to stop) |
mode |
plotting mode; if "xy", maps for time steps are plotted;
if "xt", a space-time plot is constructed (see argument |
scaleX |
integer: 0, 1 or 2; when |
auto.key |
see the |
main |
character; plot title, use |
key.space |
character; see xyplot |
scales |
scales drawing; see |
xlab |
x-axis label |
ylab |
y-axis label |
type |
character; use 'l' for lines, 'p' for symbols, 'b' for both lines and symbols |
do.repeat |
logical; repeat the animation in an infinite loop? |
range.expand |
numeric; if |
number |
number of time intervals, equally spaced |
tcuts |
time cuts in units of |
sp.layout |
list or NULL; see spplot |
... |
arguments passed on to spplot in case of
plotting objects of class |
xlim |
numeric, x range |
ylim |
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.
