Calculates the fraction of incomparable pairs in a partial order.

incomparable_pairs(P)

## Arguments

P A partial order as matrix object, e.g. calculated with neighborhood_inclusion or positional_dominance.

## Value

Fraction of incomparable pairs in P.

## Examples

library(igraph)
g <- sample_gnp(100,0.1)
P <- neighborhood_inclusion(g)
comparable_pairs(P)#> [1] 0# All pairs of vertices are comparable in a threshold graph
tg <- threshold_graph(100,0.3)
P <- neighborhood_inclusion(g)
comparable_pairs(P)#> [1] 0
