pas_filterArea: Rectangle area filtering for PurpleAir Synoptic objects

In MazamaScience/AirSensor2: Process and Display Data from Air Quality Sensors

Rectangle area filtering for PurpleAir Synoptic objects

Description

Filters pas object sensors based on a bounding box.

Usage

pas_filterArea(pas = NULL, w = NULL, e = NULL, s = NULL, n = NULL)

Arguments

pas	PurpleAir Synoptic pas object.
w	West edge of area bounding box (deg E).
e	East edge of area bounding box (deg E).
s	South edge of area bounding box (deg N).
n	North edge of area bounding box (deg N).

Value

A subset of the given pas object containing only records within the bounding box. This includes sensors located precisely on a boundary.
