Hey!
As y'all may have seen, we have a new pageviews API, with much finer granularity and better recall than the existing data. Since I had advance notice of the release, I was able to put together an R client already - you can get it at https://github.com/Ironholds/pageviews if R is your language of choice, and it'll be up on CRAN shortly.
Thanks,
