AnnData.var_vector(k, *, layer=None)

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:

layer : str, NoneOptional[str]

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

Return type:

ndarrayndarray

  • A one dimensional nd array, with values for each var in the same order
  • as .var_names.
