## S3 method for class 'splitppp':
plot(x, \dots, main, arrange=TRUE,
nrows=NULL, ncols=NULL,
main.panel=NULL, mar.panel=c(2,1,1,2),
panel.begin=NULL, panel.end=NULL, panel.args=NULL, plotcommand="plot",
adorn.left=NULL, adorn.right=NULL, adorn.top=NULL, adorn.bottom=NULL,
adorn.size=0.2,
equal.scales=FALSE)
split.ppp
.plot.ppp
which control the
appearance of each plot panel.arrange=TRUE
)
or plot them individually in a succession of frames
(arrange=FALSE
).arrange=TRUE
).
You can specify either or both of these numbers.mar
controlling the size
of the margins outside each plot panel.
See the help file for par
.equal.scales=FALSE
and increase the values of mar.panel
.plot
method for the class "splitppp"
.
It is typically used to plot the result of the function
split.ppp
but it may also be used to plot any list
of point patterns created by the user. The argument x
should be a named list of point patterns
(objects of class "ppp"
, see ppp.object
).
Each of these point patterns will be plotted in turn
using plot.ppp
.
The arguments panel.begin
and panel.end
may be functions that will be executed before and after each panel is plotted.
They will be called as panel.begin(i, y, main=main.panel[i])
and panel.end(i, y, add=TRUE)
.
Alternatively, panel.begin
and panel.end
may be objects
of some class that can be plotted
with the generic plot
command. They will be plotted before and
after each panel is plotted.
If equal.scales=FALSE
(the default), then the
plot panels will have equal height on the plot device
(unless there is only one column of panels, in which case
they will have equal width on the plot device). This means that the
objects are plotted at different physical scales, by default.
If equal.scales=TRUE
, then the dimensions of the
plot panels on the plot device will be proportional
to the spatial dimensions of the
corresponding components of x
. This means that the
objects will be plotted at approximately equal physical scales.
If these objects have very different spatial sizes,
the plot command could fail (when it tries
to plot the smaller objects at a tiny scale), with an error
message that the figure margins are too large.
The objects will be plotted at exactly equal physical scales, and exactly aligned on the device, under the following conditions:
