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]], ...).
rel_graph(x, pord, ...)Returns a square logical matrix.
dimnames of the matrix correspond
to names of x.
list with elements to compare, preferably named
a function with two arguments, returning a single Boolean value,
e.g., pord_spread,
pord_nd, or pord_weakdom
additional arguments passed to pord
