My {cdcfluview} package started tossing erros on CRAN just over a week ago when the CDC added an extra parameter to one of the hidden API endpoints that the package wraps. After a fairly hectic set of days since said NOTE came, I had time this morning to poke at ...

The last post showed how to work with the macOS mdls command line XML output, but with {swiftr} we can avoid the command line round trip by bridging the low-level Spotlight API (which mdls uses) directly in R via Swift. If you’ve already played with {swiftr} before but were ...

Guillaume Pressiat (@GuillaumePressiat) did a solid post & video on using Selenium to scrape a paginated table from understat[.]com/league/EPL/2020 (I just cannot bring myself to provide an active link to any SportsBall site). He does a great job walking folks through acquiring & orchestrating the heavy dependency that is ...

Brim Security maintains a free, Electron-based desktop GUI for exploration of PCAPs and select cybersecurity logs: along with a broad ecosystem of tools which can be used independently of the GUI. The standalone or embedded zqd server, as well as the zq command line utility let analysts run ZQL (a ...

Horrible puns aside, hopefully everyone saw the news, earlier this week, from @thomasp85 on the evolution of modern typographic capabilities in the R ecosystem. Thomas (and some cohorts) has been working on {systemfonts}, {ragg}, and {textshaping} for quite a while now, and the — shall we say tidyglyphs ecosystem — is super-ready ...

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 ...
