Provides a logical value on whether the graph is weighted. A graph is considered to be weighted when it contains edges that all have a edge weight attribute with numerical values assigned for all edges.

is_graph_weighted(graph)

Arguments

graph

a graph object of class dgr_graph.

Value

a logical value.

Examples

# Create a graph where the edges have # a `weight` attribute graph <- create_graph() %>% add_cycle(n = 5) %>% select_edges() %>% set_edge_attrs_ws( edge_attr = weight, value = c(3, 5, 2, 9, 6)) %>% clear_selection() # Determine whether the graph # is a weighted graph graph %>% is_graph_weighted()
#> [1] TRUE
# Create graph where the edges do # not have a `weight` attribute graph <- create_graph() %>% add_cycle(n = 5) # Determine whether this graph # is weighted graph %>% is_graph_weighted()
#> [1] FALSE
