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
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
