I hope you don?t mind us using this mailing list for a small advertisement, but we think it is most relevant for this group: We'd like to invite you to RIOT 2017 - the 3rd workshop on R Implementation, Optimization and Tooling [1]. It will take place co-located with, and during, useR! 2017 in Brussels on July 5th. RIOT is an excellent venue for deep technical discussions about R implementations, tools, optimizations and extension, and will be very interesting for anyone interested in what?s under the hood of R implementations. Regards, Lukas Stadler (Oracle), Jan Vitek (Northeastern), Alexander Bertram (BeDataDriven) [1] http://riotworkshop.github.io/ <http://riotworkshop.github.io/> [[alternative HTML version deleted]]
