Download recent PM2.5 monitoring data

Source: R/monitor_downloadLatest.R

Downloads 'latest' 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 daily updates covering the most recent 45 days, use monitor_downloadDaily().

For data extended more than 45 days into the past, use monitor_downloadAnnual().
