From a graph object of class dgr_graph or a node data frame, set node
attribute properties for nodes present in a node selection.
This function makes use of an active selection of nodes (and the function
ending with _ws hints at this).
Selections of nodes can be performed using the following node selection
(select_*()) functions: select_nodes(), select_last_nodes_created(),
select_nodes_by_degree(), select_nodes_by_id(), or
select_nodes_in_neighborhood().
Selections of nodes can also be performed using the following traversal
(trav_*()) functions: trav_out(), trav_in(), trav_both(),
trav_out_node(), trav_in_node(), trav_out_until(), or
trav_in_until().
Arguments
- graph
A graph object of class
dgr_graph.- node_attr
The name of the attribute to set.
- value
The value to be set for the chosen attribute for the nodes in the current selection.

Examples
# Create a simple graph
graph <-
create_graph() %>%
add_path(n = 6)
# Select specific nodes from the graph and
# apply the node attribute `color = blue` to
# those selected nodes
graph <-
graph %>%
select_nodes_by_id(
nodes = 1:4) %>%
trav_out() %>%
set_node_attrs_ws(
node_attr = color,
value = "blue")
# Show the internal node data frame to verify
# that the node attribute has been set for
# specific node
graph %>% get_node_df()
#> id type label color
#> 1 1 <NA> 1 <NA>
#> 2 2 <NA> 2 blue
#> 3 3 <NA> 3 blue
#> 4 4 <NA> 4 blue
#> 5 5 <NA> 5 blue
#> 6 6 <NA> 6 <NA>
