Selectivity Curves

Description

Establish and possibly draw the different selectivity curves

Usage

selectivity(x, type = "Q(T)", plot = TRUE, new = TRUE, 
zlab = "z", xlim = NA, ...)

Arguments

x

Array of values (considered as equally weighted)

type

Type of the selectivity curve:

  • B(z) : Conventional benefit as a function of the Cutoff

  • Q(T) : Metal quantity as a function of the Tonnage

  • Q(z) : Metal quantity as a function of the Cutoff

  • T(z) : Tonnage as a function of the Cutoff

  • m(z) : Average Grade as a function of the Cutoff

plot

When switched ON, the selectivity curve is represented graphically

new

When switched ON, the graphic page is erased before the selectivity curve is represented.

zlab

Name given to the variable axis

xlim

Bounds along the variable

...

Arguments passed to the plot function

Value

A matrix with columns containing the two coordinates of the selectivity curve

Examples

data(Example_parcelles100) # Data set 100 data
data(Example_parcelles25)  # Data set 25 data
selectivity(Example_parcelles100) # Draw Metal/Tonnage for 100 samples
selectivity(Example_parcelles25,new=FALSE) #Overlay the Metal/Tonnage for 25 samples
rm(Example_parcelles100,Example_parcelles25) # Cleanup
