| Parameters: |
- exp (Experiment) – Input experiment object.
- field (str) – the column name of the sample or feature metadata tables
- select (None, Callable, or list/set/tuple-like) – select what to keep based on the value in the specified field.
if it is a callable, it accepts a 1D array and return a
boolean array of the same length; if it is a list/set/tuple-like object,
keep the samples with the values in the field column included
in the select; if it is None, filter out the NA.
- axis (0, 1, 's', or 'f', optional) – the field is on samples (0 or ‘s’) or features (1 or ‘f’) metadata
- negate (bool, optional) – discard instead of keep the select if set to True
- inplace (bool, optional) – do the filtering on the original
Experiment object or a copied one.
