EdgeFrame download

---

download(self, n=100, offset=0, columns=None)

Download a frame from the server into client workspace.

Parameters:

n : int (default=100)

The number of rows to download to the client

offset : int (default=0)

The number of rows to skip before copying

columns : list (default=None)

Column filter, the names of columns to be included (default is all columns)

Returns:

: pandas.DataFrame

A new pandas dataframe object containing the downloaded frame data

Copies an trustedanalytics Frame into a Pandas DataFrame.

Examples

Frame my_frame accesses a frame with millions of rows of data. Get a sample of 500 rows:

>>> pandas_frame = my_frame.download( 500 )

We now have a new frame accessed by a pandas DataFrame pandas_frame with a copy of the first 500 rows of the original frame.

If we use the method with an offset like:

>>> pandas_frame = my_frame.take( 500, 100 )

We end up with a new frame accessed by the pandas DataFrame pandas_frame again, but this time it has a copy of rows 101 to 600 of the original frame.
