plotExceed.array: 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
