Because a good C++ basis goes a darn long way...
Also github.com/QuantStack/xtenso… (but non-standard R packaging still makes me cry)
@wuoulf showing off xtensor work, for C++ library writers wanting to use either #Python or #JuliaLang. Interesting stuff at #JuliaCon2017! 🤓

Easy:
R> paste(rep(letters[1:3], 3), rep(letters[24:26], each=3), sep="")
[1] "ax" "bx" "cx" "ay" "by" "cy" "az" "bz" "cz"

A few other good hints in here, and some things I have a different view of. Generally a good blog though.

Neat idea. Maybe rewrite with fewer dependencies (Python binary?). Would be great via docopt and littler.

Use #rstats from the command line? Easily turn functions into apps with aargh github.com/jeremystan/aargh

Too late for 2017 -- but this could have made a neat @Google #GSOC2017 project.
So thumbs up from #Rstats and #Rcpp. Volunteers needed.
Hoping to get Rcpp-based #rstats bindings up soon in addition to the already existing #python and #julialang ! cc @romain_francois
