Lecture slides for my 'Data Science Programming Methods' course STAT 447 from this Fall 2021 at U of Illinois are now accessible via stat447.com covering shell (incl sed/awk), markdown, git(hub), sql, lots of #Rstats up to packaging, and Docker. Enjoy!

Playing with a motivating intro example for STAT 447 (which returns next month), here is a graph of the most popular songs in the US over the last two weeks. Can you tell what season it is right now? 🙃 This builds on an example by @bkeegan but redone in #rstats.

PSA: If you do frequent builds via `docker`, and notice less and less free diskspace, consider running docker system prune and compare the before/after with `docker system df`. I recovered almost 100 gb on my machine. #rstats #datascience

Dear @capitalone your updated bill pay interface is inferior to the previous version. Not being able to suspect a single payment in a series, and not being able to edit a payment series are serious shortcomings.

#r2u thanks a "yuge" tech company for unwavering support downloading _over five-thousand CRAN #rstats packages as Ubuntu .deb binaries_ every day at the same time from our main mirror. Aren't cronjobs lovely? 😘 #r2u. Fast. Easy. Reliable. Also for $200 billion companies.

This package uses approximate nearest neighbours via {RcppAnnoy}, {RcppHNSW} (thanks to @eddelbuettel) and {mlpack} which are very fast and scalable (thanks to {text2vec}) and the {igraph} package to create blocks for comparisons.
