Rectangle area filtering for PurpleAir Synoptic objects

Filters pas object sensors based on a bounding box.

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.
