@ctanes Can you please fill in some of the blanks here, I'm not sure about wording/structure for certain things. There's a vignette that I figure can show how to parse the raw data files you provided (here). Or maybe it's not worth including this as a vignette, just a better commented R file in data-raw? Your thoughts?
