plot.stlgcppm: Plot of the fitted intensity of a LGCP model

Description

The function plots the fitted intensity, displayed both in space and in space and time. In the case of local covariance parameters, the function returns the mean of the random intensity, displayed both in space and in space and time.

Usage

# S3 method for stlgcppm
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 stlgcppm
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
