anndata.AnnData.obs_vector

AnnData.obs_vector(k, /, *, layer=None)

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

Deprecated since version 0.13: Use anndata.acc.A instead of obs_vector. E.g. vec = adata[A.obs['foo']] or vec = adata[A.layers['l']['bar', :]]

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:

anndata.typing.InMemoryArray | ExtensionArray | Variable

Returns:

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