Set multiple vertex attributes

Usage

set_vertex_attrs(graph, ..., index = V(graph))

Arguments

graph

The graph.

...

<dynamic-dots> Named arguments, where the names are the attributes

index

An optional vertex sequence to set the attributes of a subset of vertices.

Value

The graph, with the vertex attributes added or set.

Examples

g <- make_ring(10)
set_vertex_attrs(g, color = "blue", size = 10, name = LETTERS[1:10])
#> IGRAPH a405b1a UN-- 10 10 -- Ring graph
#> + attr: name (g/c), mutual (g/l), circular (g/l), color (v/c), size
#> | (v/n), name (v/c)
#> + edges from a405b1a (vertex names):
#>  [1] A--B B--C C--D D--E E--F F--G G--H H--I I--J A--J
# use splicing if suplying a list
x <- list(color = "red", name = LETTERS[1:10])
set_vertex_attrs(g, !!!x)
#> IGRAPH a405b1a UN-- 10 10 -- Ring graph
#> + attr: name (g/c), mutual (g/l), circular (g/l), color (v/c), name
#> | (v/c)
#> + edges from a405b1a (vertex names):
#>  [1] A--B B--C C--D D--E E--F F--G G--H H--I I--J A--J
# to set an attribute named "index" use `:=`
set_vertex_attrs(g, color = "blue", index := 10, name = LETTERS[1:10])
#> IGRAPH a405b1a UN-- 10 10 -- Ring graph
#> + attr: name (g/c), mutual (g/l), circular (g/l), color (v/c), index
#> | (v/n), name (v/c)
#> + edges from a405b1a (vertex names):
#>  [1] A--B B--C C--D D--E E--F F--G G--H H--I I--J A--J
