mts_filterMeta: General purpose metadata filtering for _mts_ time series...

In MazamaTimeSeries: Core Functionality for Environmental Time Series

General purpose metadata filtering for mts time series objects

Description

A generalized metadata filter for mts objects to choose rows/cases where conditions are true. Multiple conditions are combined with & or separated by a comma. Only rows where the condition evaluates to TRUE are kept. Rows where the condition evaluates to FALSE or NA are dropped.

If an empty mts object is passed in, it is immediately returned, allowing for multiple filtering steps to be piped together and only checking for an empty mts object at the end of the pipeline.

Usage

mts_filterMeta(mts, ...)

Arguments

mts	mts object.
...	Logical predicates defined in terms of the variables in mts$meta.

Value

A subset of the incoming mts time series object. (A list with meta and data dataframes.)

Note

Filtering is done on variables in mts$meta.
