reorder_graph_actions {DiagrammeR} | R Documentation |
Execute the graph actions stored in
the graph through the use of the
add_graph_action()
function. These actions
will be invoked in order and any errors
encountered will trigger a warning message and
result in no change to the input graph.
reorder_graph_actions(graph, indices)
graph |
a graph object of class
|
indices |
a numeric vector that provides the new ordering of graph actions. This vector can be the same length as the number of graph actions, or, of shorter length. In the latter case, the ordering places the given items first and the remaining actions will follow. |
a graph object of class dgr_graph
