And the rocker/r-base:4.0.0 image (based on @Debian testing plus experimental plus a small PPA of mine with R 4.0.0 compatible packages for r-recommended) is now live. #rstats #rocker

New #Rcpp record: Used by every other compiled CRAN #Rstats package. I.e. we now have 50% coverage among packages using compiled code. And a little under 1/8th of all CRAN packages. [Note: So far didn't exclude dupes which CRAN has e.g. pre-release, will fix going forward.]

The R 4.0.0 source packages for @Debian are uploaded. The transition from 'experimental' into @Debian proper will take time; 'rocker/r-base:4.0.0' will be up once we have .deb binaries. And @Ubuntu builds of R 4.0.0 for 18.04, 19.10 and 20.04 are in my ppa:edd/r-4.0. #rstats

#Rcpp just hit 1000 citations per @google scholar -- thanks so much to everybody who relies on #Rcpp to integrate #Rstats and #Cpp, and of course especially to those who contribute code, documentation, testing or suggestions. /cc @jstatsoft

At @celebRtion2020 the @HeathrTurnr talk used a (free, iirc) service straight off (iirc) github which transcribed live. Pretty high quality---not as good as (human) professional service but impressive. An alternative? The video only shows slides though youtube.com/watch?v=BbpkKzz7…

Good tweet to keep around for students. Picking dependencies matters. Sometimes change is unavoidable, but selection of tools is part of good design. Eg @CRANberriesFeed runs (by now hourly) for close to thirteen years, and I never have to touch the (base R + RSQLite) code.

And just ... wow. Look at the API using Modern C++ on the left, and the output on the right. Not only faster than everything else but now also expressive. (Minimally tweaked from the example the blog post by @lemire). #rstats #rcpp
