EdgeFrame add_edges

---

add_edges(self, source_frame, column_name_for_source_vertex_id, column_name_for_dest_vertex_id, column_names=None, create_missing_vertices=False)

Add edges to a graph.

Parameters:

source_frame : Frame

Frame that will be the source of the edge data.

column_name_for_source_vertex_id : unicode

column name for a unique id for each source vertex (this is not the system defined _vid).

column_name_for_dest_vertex_id : unicode

column name for a unique id for each destination vertex (this is not the system defined _vid).

column_names : list (default=None)

Column names to be used as properties for each vertex, None means use all columns, empty list means use none.

create_missing_vertices : bool (default=False)

True to create missing vertices for edge (slightly slower), False to drop edges pointing to missing vertices. Defaults to False.

Includes appending to a list of existing edges.
