pat_loadLatest: Load PurpleAir time series data for a week

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

Load PurpleAir time series data for a week

Description

A pre-generated PurpleAir Timeseries pat object will be loaded containing data for the most recent 7- or 45-day interval. Data are loaded from the archive set with either setArchiveBaseUrl() or setArchiveBaseDir() for locally archived files.

Usage

pat_loadLatest(id = NULL, label = NULL, pas = NULL, days = 7)

Arguments

id	PurpleAir sensor 'deviceDeploymentID'.
label	PurpleAir sensor 'label'.
pas	PurpleAir Synoptic pas object.
days	Number of days of data to include (7 or 45).

Value

A PurpleAir Timeseries pat object.

Note

Archive file names are generated with a unique "device-deployment" identifier by combining a unique location ID with a unique device ID. These deviceDeploymentID identifiers guarantee that movement of a sensor will result in the creation of a new time series.

Users may request a pat object in one of two ways:

1) Pass in id with a valid a deviceDeploymentID

2) Pass in both label and pas so that the deviceDeploymentID can be looked up.
