In mplex/multiplex: Algebraic Tools for the Analysis of Multiple Social Networks

Coerce to a Semigroup Object

Description

A generic function for coercing an R object to a semigroup class.

Usage

as.semigroup(x, gens = NA, lbs, numerical, edgeT)

Arguments

x	an array representing the semigroup
gens	array or vector representing the semigroup generators
lbs	(optional) label strings for the semigroup
numerical	(optional and logical) should the semigroup have numerical format?
edgeT	(optional, logical, and experimental) is ‘x’ an edge table?

Details

Since many of the functions in the multiplex package require an object of the 'Semigroup' class, this function produces this class object from an array representing the semigroup structure.

Value

An object of the 'Semigroup' class

ord	a number with the dimension of the semigroup
st	the strings, i.e. a vector of the unique relations
gens	the semigroup generators
S	the multiplication table of the semigroup

Examples

## create labeled multiplication table data
s <- matrix(data=c(1, 1, 1, 3, 3, 3, 3, 3, 3), nrow=3, ncol=3, byrow=TRUE)
attr(s, "dimnames") <- list(1:3,1:3)

## make a semigroup object
as.semigroup(s)
