Use this if you are using igraph from R
This is a helper function that simplifies adding and deleting edges to/from graphs.
See details below.
edges is an alias for
When adding edges via
+, all unnamed arguments of
edges) are concatenated, and then passed to
add_edges. They are interpreted as pairs of vertex ids,
and an edge will added between each pair. Named arguments will be
used as edge attributes for the new edges.
When deleting edges via
-, all arguments of
edges) are concatenated via
c() and passed to
A special object that can be used with together with igraph graphs and the plus and minus operators.
g <- make_ring(10) %>% set_edge_attr("color", value = "red") g <- g + edge(1, 5, color = "green") + edge(2, 6, color = "blue") - edge("8|9") E(g)[] g %>% add_layout_(in_circle()) %>% plot() g <- make_ring(10) + edges(1:10) plot(g)
