The past two posts have (lightly) introduced how to use compiled Swift code in R, but they’ve involved a bunch of “scary” command line machinations and incantations. One feature of {Rcpp} I’ve always ???? is the cppFunction() (“r-lib” zealots have a similar cpp11::cpp_function()) which lets one experiment ...

Last week I introduced a new bookdown series on how to embed R into a macOS Swift application. The initial chapters focused on core concepts and showed how to build a macOS compiled, binary command line application that uses embedded R for some functionality. This week, a new chapter is ...

Over Christmas break I teased some screencaps: A more refined #rstats #swift "SwiftR" example. Simple Image view + some text views, a color picker and a button that runs R-in-Swift code (like {reticulate} does for Python in R) Note no ssd/hd storage round-trip for the plot. Code snippet: https://t....

While the future of the Apache Drill ecosystem is somewhat in-play (MapR — a major sponsoring org for the project — is kinda dead), I still use it almost daily (on my local home office cluster) to avoid handing over any more money to Amazon than I/we already do. The latest (...

It’s been a while since I’ve posted anything R-related and, while this one will be brief, it may be of use to some R folks who have taken the leap into Big Sur and/or Apple Silicon. Stay to the end for an early Christmas ????! Big Sur Report ...

The CDC continues to “deliver” in 2020, this time by changing the JSON response of one of the hidden APIs that my {cdcfluview} package wraps. CDC: So helpful! It was a quick fix, and version 0.9.2 passed automated CRAN checks in ~9.42 minutes! ???? the CRAN team! Plus, a special shout-out to Ian-McGovern (GH ...

The Marshall Project has a solid story and set of visualizations on the impact of COVID-19 in U.S. prisons. They keep the data (and vis) regularly updated. They do great work and this is an important topic, but this visualization breaks my “ordered grid” OCD: To be fair, it’...

R 4.0.0 has been out for a while, now, and — apart from a case where merge() was slower than dirt — it’s been really stable for at least me (I use it daily on macOS, Linux, and Windows). Sure, it came with some headline-grabbing features/upgrades, but I’ve started looking ...

The United States Centers for Disease Control (CDC from now on) has setup two new public surveillance resources for COVID-19. Together, COVIDView and COVID-NET provide similar weekly surveillance data as FluView does for influenza-like illnesses (ILI). The COVIDView resources are HTML tables (O_O) and, while the COVID-NET interface provides ...

Waffle House announced it was closing hundreds of stores this week due to SARS-Cov-2 (a.k.a COVID-19). This move garnered quite a bit of media attention since former FEMA Administrator Craig Fugate used the restaurant chain as both an indicator of the immediate and overall severity of a natural ...
