rel_graph: Create an Adjacency Matrix Representing a Binary Relation

In Rexamine/agop: Aggregation Operators and Preordered Sets

Create an Adjacency Matrix Representing a Binary Relation

Description

Returns a binary relation that represents results of comparisons with pord of all pairs of elements in x. We have ret[i,j] == pord(x[[i]], x[[j]], ...).

Usage

rel_graph(x, pord, ...)

Arguments

x	list with elements to compare, preferably named
pord	a function with two arguments, returning a single Boolean value, e.g., pord_spread, pord_nd, or pord_weakdom
...	additional arguments passed to pord

Value

Returns a square logical matrix. dimnames of the matrix correspond to names of x.
