set_node_attr_to_display | R Documentation |
Set a node attribute type to display as node text when calling the
render_graph()
function. This allows for display of different types of node
attribute values on a per-node basis. Without setting the display
attribute, rendering a graph will default to printing text from the label
attribute on nodes. Setting the display
node attribute with this function
for the first time (i.e., the display
column doesn't exist in the graph's
internal node data frame) will insert the attr
value for all nodes
specified in nodes
and a default value (default
) for all remaining nodes.
