Base URL for pre-generated data

This package maintains an internal archive base URL which users can set using setArchiveBaseUrl(). Alternatively, if an archive of pre-generated data files is availalbe locally, users can set the location of this directory withsetArchiveBaseDir().

To avoid internet latency, specification of BASE_DIR will always take precedence over specification of BASE_URL. Known base URLs include:

• https://airsensor.aqmd.gov/PurpleAir/v1

Package functions that load pre-generated data files download data from this URL. These functions include:

• pas_load()

• pat_load()

• pat_loadLatest()

• pat_loadMonth()

• sensor_load()
