plot.stppm {stopp}

Plot of the fitted intensity of a spatio-temporal Poisson process model

Description

The function plots the fitted intensity, displayed both in space and in space and time.

Usage

## S3 method for class 'stppm'
plot(
  x,
  scaler = c("silverman", "IQR", "sd", "var"),
  do.points = TRUE,
  print.bw = FALSE,
  zap = 1e-05,
  par = TRUE,
  ...
)

Arguments

x

An object of class stppm

scaler

Optional. Controls the value for a scalar representation of the spatial scale of the data. Either a character string, "silverman" (default), "IQR", "sd", or "var"; or positive numeric value(s). See OS.

do.points

Add points to plot

print.bw

It prints the estimated oversmoothing (OS) bandwidth selector

zap

Noise threshold factor (default to 0.00001). A numerical value greater than or equal to 1. If the range of pixel values is less than zap * .Machine$double.eps, the image will be treated as constant. This avoids displaying images which should be constant but contain small numerical errors.

par

Default to TRUE.

...

additional unused argument
