## S3 method for class 'stpp'
plot(x, s.region=NULL, t.region=NULL, mark=FALSE, mark.cexmin=0.4,
     mark.cexmax=1.2, mark.col=1, ...)

Arguments

x

any object of class stpp in spatio-temporal point format.

s.region

two-column matrix specifying polygonal region containing all data locations. If s.region is missing, the default limits are considered.

t.region

vector containing the minimum and maximum values of the time interval. If t.region is missing, the default limits are considered.

mark

Logical. If FALSE (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.

mark.cexmin, mark.cexmax

range of the size of the plotting symbol when mark=TRUE.

mark.col

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 function plot. Typical argument is pch.

Value

None
