geost.base.LayeredData.select_by_condition#

LayeredData.select_by_condition(condition: Any, invert: bool = False)[source]#

Select data using a manual condition that results in a boolean mask. Returns the rows in the data where the ‘condition’ evaluates to True.

Parameters:

  • condition (list, pd.Series or array like) – Boolean array like object with locations at which the values will be preserved, dtype must be ‘bool’ and the length must correspond with the length of the data.

  • invert (bool, optional) – If True, the selection is inverted so rows that evaluate to False will be returned. The default is False.

Returns:

New instance containing only the data objects selected by this method.

Return type:

LayeredData

Examples

Select rows in borehole data that contain a specific value:

>>> boreholes.select_by_condition(boreholes["lith"]=="V")

Or select rows in the borehole data that contain a specific (part of) string or strings:

>>> boreholes.select_by_condition(boreholes["column"].str.contains("foo|bar"))
