Sipping some of the C++ cocktail with #Rcpp (@eddelbuettel et al.) in #R.
I addressed a bottleneck:
Mean in msec
R: 109720.593
C++: 212.177
C++ won this race: ~500 times faster!
First time tasting C++, it might be addictive..

And the @Debian (source) package has been updated, and uploaded.
Expect binaries for two dozen architectures 'soon' and, if you care, watch this page for them: buildd.debian.org/status/pac…

Spot on. Cf Chambers (2016, Sec 1.1, "Three Principles"):
- Everything that exists in R is an object.
- Everything that happens in R is a function call.
- Interfaces to other software are part of R.
So a Big Yes!! to XR, #Rcpp, reticulate, ...
#rstats
I highly recommend trying to use #reticulate and #Rcpp to call other languages in #Rstats. We have a luxury of tools and should make the best use of them. There is absolutely no need to accept the limitations of one toolset when others are on hand to use when more appropriate.

We need more comparitive analyses -- so thumbs up for @ilustat for the "how to" on analysing this data set with both
