From a graph object of class dgr_graph or a node data frame, set node attribute properties for nodes present in a node selection.

Selections of nodes can be performed using the following 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 functions: (trav_...): trav_out(), trav_in(), trav_both(), trav_in_node(), trav_out_node().

set_node_attrs_ws(graph, node_attr, value)

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.

Value

a graph object of class dgr_graph.

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>
