plotExceed.array: plotExceed.array function

In lgcp: Log-Gaussian Cox Process

plotExceed.array function

Description

Function for plotting exceedance probabilities stored in array objects. Used in plotExceed.lgcpPredict.

Usage

## S3 method for class 'array'
plotExceed(
  obj,
  fun,
  lgcppredict = NULL,
  xvals = NULL,
  yvals = NULL,
  window = NULL,
  cases = NULL,
  nlevel = 64,
  ask = TRUE,
  mapunderlay = NULL,
  alpha = 1,
  sub = NULL,
  ...
)

Arguments

obj	an object
fun	the name of the function used to compute exceedances (character vector of length 1). Note that the named function must be in memory.
lgcppredict	an object of class lgcpPredict that can be used to supply an observation window and x and y coordinates
xvals	optional vector giving x coords of centroids of cells
yvals	optional vector giving y coords of centroids of cells
window	optional obervation window
cases	optional xy (n x 2) matrix of locations of cases to plot
nlevel	number of colour levels to use in plot, default is 64
ask	whether or not to ask for a new plot between plotting exceedances at different thresholds.
mapunderlay	optional underlay to plot underneath maps of exceedance probabilities. Use in conjunction with rainbow parameter 'alpha' (eg alpha=0.3) to set transparency of exceedance layer.
alpha	graphical parameter takign values in [0,1] controlling transparency of exceedance layer. Default is 1.
sub	optional subtitle for plot
...	additional arguments passed to image.plot

Value

generic function returning method plotExceed
