Calculates the size of a set

Source: R/AllGenerics.R, R/length.R

Assuming that the fuzzy values are probabilities, calculates the probability of being of different sizes for a given set.

set_size(object, sets = NULL)

# S4 method for TidySet
set_size(object, sets = NULL)

Arguments

object

A TidySet object.
sets

The sets from which the length is calculated.

Value

A list with the size of the set or the probability of having that size.

    sets = c(rep("A", 5), "B", "C"),
    elements = c(letters[seq_len(6)], letters[6]),

)
a <- tidySet(relations)
