Partial ranking as directed graph
Turns a partial ranking into a directed graph. An edge (u,v) is present if P[u,v]=1
, meaning that u is dominated by v.
dominance_graph(P)
P
: A partial ranking as matrix object calculated with neighborhood_inclusion
or positional_dominance .
Directed graph as an igraph object.
library(igraph) g <- threshold_graph(20, 0.1) P <- neighborhood_inclusion(g) d <- dominance_graph(P) ## Not run: plot(d) ## End(Not run) # to reduce overplotting use transitive reduction P <- transitive_reduction(P) d <- dominance_graph(P) ## Not run: plot(d) ## End(Not run)
