AnnData.obs_vector(k, *, layer=None)[source]#

Convenience function for returning a 1 dimensional ndarray of values from X, layers[k], or obs.

Made for convenience, not performance. Intentionally permissive about arguments, for easy iterative use.

Parameters:
k str

Key to use. Should be in var_names or obs.columns.

layer str | None (default: None)

What layer values should be returned from. If None, X is used.

Return type:

ndarray

Returns:

A one dimensional ndarray, with values for each obs in the same order as obs_names.
