pyrolite.util.time
- pyrolite.util.time.listify(df, axis=1)[source]
Consdense text information across columns into a single list.
- Parameters
df (
pandas.DataFrame) – Dataframe (or slice of dataframe) to condense along axis.axis (
int) – Axis to condense along.
- pyrolite.util.time.age_name(agenamelist, prefixes=['Lower', 'Middle', 'Upper'], suffixes=['Stage', 'Series'])[source]
Condenses an agename list to a specific agename, given a subset of ambiguous_names.
- Parameters
agenamelist (
list) – List of name components (i.e.[Eon, Era, Period, Epoch])prefixes (
list) – Name components which occur prior to the higher order classification (e.g."Upper Triassic").suffixes (
list) – Name components which occur after the higher order classification (e.g."Cambrian Series 2").
- pyrolite.util.time.import_colors(filename=PosixPath('/home/docs/checkouts/readthedocs.org/user_builds/pyrolite/checkouts/main/pyrolite/data/timescale/timecolors.csv'), delim='/')[source]
Import a list of timescale names with associated colors.
- pyrolite.util.time.timescale_reference_frame(filename=PosixPath('/home/docs/checkouts/readthedocs.org/user_builds/pyrolite/checkouts/main/pyrolite/data/timescale/geotimescale_202210.csv'), info_cols=['Start', 'End', 'Aliases'], color_info=None)[source]
Rearrange the text-based timescale dataframe. Utility function for timescale class.
- Parameters
filename (
str|pathlib.Path) – File from which to generate the timescale information.info_cols (
list) – List of columns beyond hierarchial group labels (e.g. Eon, Era..).- Returns
Dataframe containing timescale information.
- Return type
- class pyrolite.util.time.Timescale(filename=None)[source]
- text2age(entry, nulls=[None, 'None', 'none', nan, 'NaN'])[source]
Converts a text-based age to the corresponding age range (in Ma).
String-based entries return (max_age, min_age). Collection-based entries return a list of tuples.
