Yes indeed. Beauty of small group meetings. Gave the talk with 24 hours notice as @pdalgd looked at me and said "you'll talk about tomorrow, right?".

I was fortunate to meet him in person, at the first or second R conference I went to about twenty years ago---and he was still well enough to travel. In person he is very kind, very quiet and rather gentle. A giant. And he does all this sounds with severely impacted sight.

Because he gets no ♥️ here: BDR is a saint. Got a nice and quiet email pointing out one last use of sprintf in #Rcpp (we generally use snprintf; this case was safe) as macOS 13 deprecates it. I already fixed in a branch, now testing. He is so tireless, and so helpful. #rstats

Congratulations on a new release! The @Debian package has been updated (and @Ubuntu focal + jammy builds are in my PPA). QuantLib-SWIG to follow once I can rely on the library it its build.

Have you looked into `mlr3` as an alternative?

You are doing it wrong. See `example(grangertest, package="lmtest")` for a formal Granger Causality test on this. 😜 #rstats /cc @AchimZeileis

Solving “What came first the chicken or the egg?” with #RStats. whatcamefirst <- c("🥚","🐔" ) sort(whatcamefirst, decreasing = FALSE) # > [1] "🐔" "🥚" The answer is Chicken :) Mystery solved, thank you R #RStats

PSA: If your #RStats actions at @github end in a nag 'Node.js 12 actions are deprecated.' as shown belowthen do an update as shown in the second picture and use actions/checkout@v3. I so look forward to having to do that for dozens of my repositories. 🤯

Just did something I had not done in a looong time and watched "linear" (non-sports) tv: the @RonCarterBass movie just premiered on @pbs -- and it was really good. Recommended to catch on streaming soon. roncartermovie.com/

It actually extends far beyond (some) #RStats package to most (if not all) well-behaved components of the entire Unix toolchain and POSIX spec. Which is why outcries like this recent one are both rare, and justified:

I see that a bunch of system administrators (or distribution packagers) are going to set GNU Grep 3.8 on fire with the power of their minds. Spoiler: new warnings are an API change.

This will happen one week from now: the next #r2u talk at the YEGRUG in Edmonton. If you are curious about `r2u` please sign up and I will see you (remotely, of course) next week! #rstats meetup.com/edmonton-r-user-g…

A concrete example: - a colleague recently demoing / installing `tidyverse` on a RHEL cluster machine: 40+ minutes - using r2u on Ubuntu: around 20 seconds, no questions, no extra steps. It just works. Try it via Docker or in your browser via @gitpod.io (see link at repo).
