This function plot either \(xy\)-locations and cumulative distribution of the times, or a space-time 3D scatter, or the time-mark and space-mark of the spatio-temporal point pattern, through arguments style and type.
It can also plot \(xy\)-locations with time treated as a quantitative mark attached to each location, as in the previous version of the function, through argument mark (see stpp version < 2.0.0).
# S3 method for stpp
plot(x, s.region=NULL, t.region=NULL, style="generic", type="projection",
mark=NULL , mark.cexmin=0.4, mark.cexmax=1.2, mark.col=1, ...)None
Any object of class stpp in spatio-temporal point format.
Two-column matrix specifying polygonal region containing all data locations. If s.region is missing, the default limits are considered.
Vector containing the minimum and maximum values of the time interval. If t.region is missing, the default limits are considered.
Specify the kind of graphical representation. If type="projection" (default) the function plot the xy-locations and cumulative distribution of the times. If type="mark" the function plot the time-mark and space-mark. If type="scatter" the function plot space-time 3D scatter.
Two different classes of graphic styles can be chosen. If style="generic" (default) the graphics are plot by default function plot in R and if style="elegant" the graphics are plot based on the R packages ggplot2 and plot3D.
Logical. If NULL (default), xy-locations and cumulative distribution of the times are plotted. If TRUE, the time is treated as a quantitative mark attached to each location, and the locations are plotted with the size and/or colour of the plotting symbol determined by the value of the mark.
Range of the size of the plotting symbol when mark=TRUE.
Colour of the plotting symbol when mark=TRUE. If mark.col=0, all locations have the same colour specified by the usual col argument.
Otherwise, can be 1 or "black" (default), 2 or "red", 3 or "green", 4 or "blue", in which cases symbols colour is faded, and the darker corresponds to the most recent time.
Further arguments to be passed to the functions plot and scatter3D. Typical arguments are pch, theta and phi.
