VertexFrame __init__

---

__init__(self, source=None, graph=None, label=None)

Examples

Parameters:

source : (default=None)

graph : (default=None)

label : (default=None)

Given a data file, create a frame, move the data to graph and then define a new VertexFrame and add data to it:

>>> csv = ta.CsvFile("/movie.csv", schema= [('user_id', int32), ('user_name', str), ('movie_id', int32), ('movie_title', str), ('rating', str)])
>>> my_frame = ta.Frame(csv)
>>> my_graph = ta.Graph()
>>> my_graph.define_vertex_type('users')
>>> my_vertex_frame = my_graph.vertices['users']
>>> my_vertex_frame.add_vertices(my_frame, 'user_id', ['user_name', 'age'])

>>> csv = ta.CsvFile("/movie.csv", schema= [('user_id', int32),
...                                     ('user_name', str),
...                                     ('movie_id', int32),
...                                     ('movie_title', str),
...                                     ('rating', str)])
>>> my_frame = ta.Frame(csv)
>>> my_graph = ta.Graph()
>>> my_graph.define_vertex_type('users')
>>> my_vertex_frame = my_graph.vertices['users']
>>> my_vertex_frame.add_vertices(my_frame, 'user_id',
... ['user_name', 'age'])

Retrieve a previously defined graph and retrieve a VertexFrame from it:

>>> my_graph = ta.get_graph("your_graph")
>>> my_vertex_frame = my_graph.vertices["your_label"]

Calling methods on a VertexFrame:

>>> my_vertex_frame.vertices["your_label"].inspect(20)

Convert a VertexFrame to a frame:

>>> new_Frame = my_vertex_frame.vertices["label"].copy()
