elphick.geomet.sample.Sample

class elphick.geomet.sample.Sample(data=None, name=None, moisture_in_scope=True, mass_wet_var=None, mass_dry_var=None, moisture_var=None, component_vars=None, composition_units='%', components_as_symbols=True, ranges=None, config_file=None)

__init__(data=None, name=None, moisture_in_scope=True, mass_wet_var=None, mass_dry_var=None, moisture_var=None, component_vars=None, composition_units='%', components_as_symbols=True, ranges=None, config_file=None)

Parameters:

• data (Optional[DataFrame]) – The input data

• name (Optional[str]) – The name of the sample

• moisture_in_scope (bool) – Whether the moisture is in scope. If False, only dry mass is processed.

• mass_wet_var (Optional[str]) – The name of the wet mass column

• mass_dry_var (Optional[str]) – The name of the dry mass column

• moisture_var (Optional[str]) – The name of the moisture column

• component_vars (Optional[list[str]]) – The names of the chemical columns

• components_as_symbols (bool) – If True, convert the composition variables to symbols, e.g. Fe

• ranges (Optional[dict[str, list]]) – The range of valid data for each column in the data

• config_file (Optional[Path]) – The configuration file
