As we prepare for the upcoming release of Microsoft R Open, I've been preparing the list of new and updated packages for the spotlights page. This involves scanning the CRANberries feed (with gracious thanks to Dirk Eddelbuettel) for newly-released packages and significant updates to existing ones.

This is a **lot** of data to process. For context, in October 2016 alone there were 174 new packages and 629 updated packages. For the 4 months since the last MRO release, I reviewed all of the new packages and some of the updates (those with a 1.0 or 2.0 release) by hand, and selected those that are likely to be of interest to a broad segment of R users. I hope you find some useful nuggets in the list. It's likely I missed some good ones; if you know of any others that should have been included, let me know in the comments.
