episcanpy.api.pp.subsample¶
- episcanpy.api.pp.subsample(data, fraction=None, n_obs=None, random_state=0, copy=False)¶
Subsample to a fraction of the number of observations.
- Parameters
- data :
AnnData, np.ndarray, sp.sparse The (annotated) data matrix of shape n_obs × n_vars. Rows correspond to cells and columns to genes.
- fraction : float in [0, 1] or None, optional (default: None)
Subsample to this fraction of the number of observations.
- n_obs : int or None, optional (default: None)
Subsample to this number of observations.
- random_state : int or None, optional (default: 0)
Random seed to change subsampling.
- copy : bool, optional (default: False)
If an
AnnDatais passed, determines whether a copy is returned.
- data :
- Returns
Returns X[obs_indices], obs_indices if data is array-like, otherwise subsamples the passed
AnnData(copy == False) or returns a subsampled copy of it (copy == True).
