Very cool to see R playing nicely with Spark via sparklyr package. The new flex dashboarding feature out of knitr is awesome. The R/RStudio team definitely knows what they're doing and very excited to see what's next for the data science community.
Shiny is slowly expanding its dashboarding capabilities. I have rolled out dashboards with hundreds of thousands of rows which don't need any explicit pagination and can be used simultaneously by dozens of internal customers. All this spun up in a matter of hours.
