sensor_filterMeta: Metadata filtering for AirSensor objects

In MazamaScience/AirSensor: Process and Display Data from Air Quality Sensors

Metadata filtering for AirSensor objects

Description

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

Usage

sensor_filterMeta(sensor = NULL, ...)

Arguments

sensor	An AirSensor object.
...	Logical predicates defined in terms of the variables in sensor$meta.

Value

A subset of the incoming sensor.

Note

Filtering predicates are applied to the meta dataframe within the sensor object.
