snowflake.snowpark.modin.plugin.extensions.resample_overrides.Resampler.min

Resampler.min(numeric_only: bool = False, min_count: int = 0, *args: Any, **kwargs: Any) → Union[DataFrame, Series][source] (https://github.com/snowflakedb/snowpark-python/blob/v1.26.0/snowpark-python/src/snowflake/snowpark/modin/plugin/extensions/resample_overrides.py#L480-L502)

Compute minimum of resample bins.

Parameters:

  • numeric_only (bool, default False) – Include only float, int, boolean columns.

  • min_count (int, default 0) – The required number of valid values to perform the operation. If fewer than min_count non-NA values are present the result will be NA.

  • engine (str, default None) – This parameter is ignored in Snowpark pandas. The execution engine will always be Snowflake.

  • engine_kwargs (dict, default None) – This parameter is ignored in Snowpark pandas. The execution engine will always be Snowflake.

Returns:

Computed minimum of values within each resample bin.

Return type:

Series or DataFrame

Examples

For Series:

>>> lst1 = pd.date_range('2020-01-01', periods=4, freq='1D')
>>> ser1 = pd.Series([1, 2, 3, 4], index=lst1)
>>> ser1
2020-01-01    1
2020-01-02    2
2020-01-03    3
2020-01-04    4
Freq: None, dtype: int64
Copy
>>> ser1.resample('2D').min()
2020-01-01    1
2020-01-03    3
Freq: None, dtype: int64
Copy
>>> lst2 = pd.date_range('2020-01-01', periods=4, freq='S')
>>> ser2 = pd.Series([1, 2, np.nan, 4], index=lst2)
>>> ser2
2020-01-01 00:00:00    1.0
2020-01-01 00:00:01    2.0
2020-01-01 00:00:02    NaN
2020-01-01 00:00:03    4.0
Freq: None, dtype: float64
Copy
>>> ser2.resample('2S').min()
2020-01-01 00:00:00    1.0

>>> df = pd.DataFrame(data,
...      columns=["a", "b", "c"],
...      index=pd.date_range('2020-01-01', periods=4, freq='1D'))
>>> df
            a  b  c
2020-01-01  1  8  2
