monitor_downloadAnnual: Download annual PM2.5 monitoring data

In PWFSLSmoke: Utilities for Working with Air Quality Monitoring Data

Description

Downloads 'annual' data files into dataDir for later use. Downloaded versions of PWFSL monitoring .RData files allow users to work with the package without access to the internet. Once data are downloaded to dataDir, any of the data loading functions can be called with the dataDir argument to replace internet downloads with local file access.

The recommended directory for PWFSL monitoring data is "~/data/monitoring/RData".

For data during the last 45 days, use monitor_downloadDaily().

For the most recent data, use monitor_downloadLatest().

Currently supported parameters include the following:

1. PM2.5
