sampling_pick ¶

lets_plot's first-n sampling. Not applied by ggrust.

Built as lets_plot builds it, so ported code runs; rendering warns (GgrustWarning) and draws every row.

Parameters:

• n (int) –

  Number of rows to keep.

Returns:

• FeatureSpec –

  The lets_plot spec.

Examples:

>>> from ggrust import *
>>> sampling_pick(100).as_dict()
{'name': 'pick', 'n': 100}
