xarray_aggregate

PlasmaCalcs.tools.xarray_tools.xarray_agg_stats.xarray_aggregate(array, f, dim=None, *, keep=None, promote_dims_if_needed=True, missing_dims='raise', **kw_agg_f)

returns array aggregated along dim using f.

f: callable or str

function to aggregate along dim. E.g. xarray.DataArray.sum, or ‘mean’.

Call signature should be like: f(array, dim, **kw).

str –> will call getattr(array, f)(dim, **kw).

dim: None, str, or iterable of strs

apply operation along these dimensions

keep: None, str, or iterable of strs

apply operation along all except for these dimensions.

(can provide keep or dim, but not both.)

promote_dims_if_needed: bool

whether to promote non-dimension coords to dimensions.

if False, raise DimensionKeyError if any relevant coord is not already a dimension.

missing_dims: str in (‘ignore’, ‘warn’, ‘raise’)

what to do if any coord is not found:

‘ignore’ –> do nothing.

‘warn’ –> raise a warning.

‘raise’ –> raise DimensionKeyError.

if not ‘raise’, any missing dims will be skipped.

additional kwargs are passed to f.
