The code assumes that:

-- source code files are placed in the current working directory,

-- original unprocessed data files [1-3] are placed in the data subdirectory of the current working directory,

-- the RDS subdirectory exists in the current working directory (this is where RDS files are saved),

-- the Plots subdirectory exists in the current working directory (this is where plot files are saved).

The provided RDS files [4-6] may be optionally placed in the RDS subdirectory to avoid repeating the time-consuming data preparation process -- they will be used if available or re-created from the original data otherwise (but the latter may take several hours).
