positional_dominance | R Documentation |

generalized dominance relations that can be computed on one and two mode networks.

positional_dominance(A, type = "one-mode", map = FALSE, benefit = TRUE)

`A` |
Matrix containing attributes or relations, for instance calculated by indirect_relations. |

`type` |
A string which is either 'one-mode' (Default) if |

`map` |
Logical scalar, whether rows can be sorted or not (Default). See Details. |

`benefit` |
Logical scalar, whether the attributes or relations are benefit or cost variables. |

Positional dominance is a generalization of neighborhood-inclusion for
arbitrary network data. In the default case, it checks for all pairs *u,v* if
*A_{ut} ≥ A_{vt}* holds for all *t* if `benefit = TRUE`

or
*A_{ut} ≤ A_{vt}* holds for all *t* if `benefit = FALSE`

.
This form of dominance is referred to as *dominance under total heterogeneity*.
If `map=TRUE`

, the rows of *A* are sorted decreasingly (`benefit = TRUE`

)
or increasingly (`benefit = FALSE`

) and then the dominance condition is checked. This second
form of dominance is referred to as *dominance under total homogeneity*, while the
first is called *dominance under total heterogeneity*.

Dominance relations as matrix object. An entry `[u,v]`

is `1`

if u is dominated by v.
