set.func-class: Class "set.func"

Description

Class representing a set function.

Objects from the Class

Objects can be created by calls to the function set.func.

Slots

n:

Object of class numeric of length 1 equal to the number of elements of the set on which the set function is defined.

subsets:

Object of class numeric of length 2^n containing the power set of the underlying set in "natural" order. The subsets are coded as integers.

data:

Object of class numeric of length 2^n containing the coefficients of the set function in binary order.

Extends

Class superclass.set.func, directly.

Examples

## a set function
mu <- set.func(c(1:8,8:1)/8)

## the attributes of the object
mu@n
mu@data
mu@subsets

## some conversions that cannot work
if (FALSE) as.game(mu)
if (FALSE) as.capacity(mu)
if (FALSE) as.card.set.func(mu)

## some tests
is.cardinal(mu)
is.kadditive(mu,2)
is.monotone(mu)

## some transformations
conjugate(mu)
Mobius(mu)
k.truncate.Mobius(mu,2)

## summary 
Shapley.value(mu)
interaction.indices(mu)
# the same
summary(mu)

## save the set function to a file
d <- to.data.frame(mu)
if (FALSE) write.table(d,"my.set.func.csv",sep="\t")

# finally, some conversions that should work
mu <- set.func(c(0,1,1,1,2,2,2,3))
as.game(mu)
as.capacity(mu)
as.card.set.func(mu)
