Expert Aggregated Cumulative Distribution Function
Description
Compute or plot the cumulative distribution function for objects of
class "expert"
.
Usage
1 2 3 4 5 6 7 8 9 10 11 
Arguments
x 
an object of class 
digits 
number of significant digits to use, see

Fn 
an R object inheriting from 
... 
arguments to be passed to subsequent methods, e.g.

ylab 
label for the y axis. 
verticals 
see 
col.01line 
numeric or character specifying the color of the
horizontal lines at y = 0 and 1, see 
Details
The function builds the expert aggregated cumulative distribution
function corresponding to the results of expert
.
The function plot.cdf
which implements the plot
method for cdf
objects, is implemented via a call to
plot.stepfun
; see its documentation.
Value
For cdf
, a function of class "cdf"
, inheriting from the
"function"
class.
