That is a rich topic in its full generality (do you need to compile the resource or not?) when reflecting the full set of OSs (windows can be tricky). A pre-print of mine discusses it but even that cannot cover all aspects. #rstats arxiv.org/abs/1911.06416

We had a three-year pilot with RStudio Cloud 'campus-wide' (which worked well for my course) but for 'reasons' that ended. Now aiming to get a standard server (we just bought) ready in a standard rack managed by campus / college IT. Old-school can be simpler. #rstats

Very related: description of @Google's Linux distro now uses rolling @Debian releases at weekly frequency, as opposed to bi-annual @Ubuntu LTS releases taking a year to deploy firm-wide. "Rolling" incremental updates are the way to go for #Rstats too. cloud.google.com/blog/topics…

"Legit" may mean different things to different people. You are allowed to specify a constraint, but it may upset people stuck with R 4.1.* on non-Windows platforms. I would condition out the offending code. #rstats 4.1 is old-rel and will be gone in nine months anyway.

Use `as.POSIXct()` and test via `is.finite()`: > x <- as.POSIXct(Inf) > x [1] "Inf" > is.na(x) [1] FALSE > is.finite(x) [1] FALSE > #rstats

And there is a package for that too "because friends don't let friends make plain `curl` calls". cloud.r-project.org/package=…

Chambers (2016, p4): "Everything that happens in R is a function call." He called those _fundamental principles_ for a reason.

Hey @rhub_ and @RConsortium it has been a week since the gentle poke, and over two weeks since RHub turned off Windows and Linux builds. The silence is a little deafening. Nothing? Really? #rstats #concerned

This was just wonderful. First half with full orchester lead by @gabrielkahane, second half usual small band. Both parts are extraordinary. Watched the second part (from 58m onwards) three times since... As a former German + French resident (and tax payer): Danke + Merci @ARTEen

This is epic. And it reminds of my first week at work as a fresh-out-of-grad-school quant (some 25 yrs ago) where this grizzled corporate bond trader (and a legend in Canadian Fixed Income) leans over and just barks in my direction: "hey, cost center". Ah, the memories.
without a doubt, at every startup I've worked at, the first bizops hire is the beginning of the end. it's the biggest possible signal to get the fuck out of there, because in 2 months some kid is going to be asking you to fill out an OKR spreadsheet emcap.com/thoughts/bizops-wh…

Also, updating 'leaf' (or 'near-leaf') packages with no (or few) reverse dependencies is still the best at CRAN: Seven minutes net. #ThankYouCRAN #RStats It is of course also worth the occassional weekly wait (as for Rcpp), or test discussion. Quality matters, and CRAN rules.

Fantastic. Proudly reinventing @Rdatatable and calling it innovation. #Rstats 🤦

Not so. My CRANberries code has been running (now on an hourly cronjob) for fifteen years. I have owned production jobs that ran for years. CRAN ensures an absence of fundamental breakage. You can combine that with your knowledge and experience to pick packages that behave.

Achievement unlocked: A package of mine has been meme-ified in Spanish. Per Google Translates, my `anytime` package helped simplify / be an alternate for a tutorial on how to survice Ex#%l date messes. Really glad it was of help. I use it all the myself too. #rstats
Hice un tutorial sobre cómo corregir los campos de fechas en Excel en #rstats que siempre es un bardo y armé un lindo post (ponele) para compartir con la comunidad de #rstats_es y del @club_rrhh rpubs.com/Data4HR/cargar-fec…
