Class of methods to determine cutoff point for distance-distance plots; used to derive other cutoff methods later by method dispatch.
Objects could in principle be created by calls of the form new("cutoff", ...).
More frequently they are created via the generating function
cutoff, respectively via the helper functions
cutoff.sememp and cutoff.chisq.
name:object of class "character"; defaults to "empirical"
in prototype;
fct:an object of of class "function";
for this class layer, this function
must only have one argument data (which may
but need not be used to determine the cutoff point empirically);
in derived classes this restriction could be dropped, if corresponding
special methods for ddPlot are derived. Defaults to
function(data) quantile(data).
cutoff.quantile:Object of class "numeric":
a probability (in [0,1]) to determine the respective quantile
(empirical or theoretical) to plot the cutoff line; defaults
to 0.95 in prototype;
signature(object = "cutoff"):
accessor function for slot cutoff.quantile.
signature(object = "cutoff"):
replacement function for slot cutoff.quantile.
signature(object = "cutoff"):
accessor function for slot fct.
signature(object = "cutoff"):
accessor function for slot name.
