TIL: The #RStats testthat package has a `skip()` function: testthat.r-lib.org/reference/sk...

I used to comment out tests I didn't want to fix. I'd often forget about these. With skip() I get a nice reminder. Now I'll be sure to go back and fix broken tests I left for later ... yeah, later 😂

Skip a test — skip

skip_if() and skip_if_not() allow you to skip tests, immediately concluding a test_that() block without executing any further expectations. This allows you to skip a test without failure, if for some ...

Most Customer Lifetime Value (CLV) models assume customer behavior is linear.

But what if it isn't?

I built an #rstats GAM for SaaS revenue prediction that captures:
→ Nonlinear adoption curves
→ Tier-specific behaviors
→ Feature value with uncertainty

The first #rstats conference (Nor'EastR) I ever went too I sat next to three friendly strangers who opened my eyes to the wonderful R community. Those people were @jdlong.cerebralmastication.com Kirk Mettler and David Smith! Shame to see Revolution Analytics down!

Real excited that @vscode.dev can do OS notifications when Tasks finish now. I've been wanting this one for years — plenty of #rstats devs who want to be able to minimise their code editor while a chunky analysis runs!

Screenshot of Visual Studio Code changlog says:

Tasks
OS notification for long-running task completion
Setting: task.notifyWindowOnTaskCompletion
When a user-initiated, long-running task completes while the VS Code window is not focused, an OS badge and notification toast are shown. Selecting the notification focuses the window where the task completed. You can configure this behavior with the task. notifyWindowOnTaskCompletion setting.

This is why I saved my favorite #rstats blog posts in PDF to @zotero.org, together with a link to the site on @archive.org

web.archive.org/web/20250328...

Searching for "Revolutions" on @r-bloggers.bsky.social should return all the posts I think.

#rstats
It's charming the R versions are named with some sort of reference to Peanuts characters. The name for R 4.5.1, "Great Square Root" was interesting, so I asked Google AI-- maybe Snoopy solved a problem with a square root sometime?

Here's their answer. Untrained on Peanuts? Hallucinating?

AI OVERVIEW for the prompt peanuts cartoon "Great Square Root"

The phrase "Great Square Root" does not appear to be a famous quote or a specific storyline from the Peanuts comic strip. It is possible the phrase is a misremembering or a combination of different elements, as there is no prominent "Great Square Root" character or storyline in Peanuts.

The R programming language uses Peanuts comic strip characters for its version names.

Some of the R version names have included character names like "Great Square Root" in the past.
It's possible the user is associating a programming-related term with the comic strip due to the language's use of Peanuts names.

Didn't know that {skimr::skim} worked an arrow object. It's pretty cool, but it hits your RAM pretty hard. That's only a 70MB directory of parquet files, and my RAM usage went up by ~1.3GB. #rstats Code: https://ray.so/fCoXwso

Here is an example of why the #rstats `qlcal` package (updated earlier today, see below) is useful as it contains six _business / exchange_ calendars thay can answer the question "was yesterday (i.e. Columbus Day) a holiday in the US" in an affirmative "not for stock or energy markets".

$R code (and output) using just-updated package `qlcal` to answer if yesterday (i.e. Columbus Day) was a holiday: > uscals <- grepv("UnitedStates", qlcal::calendars) > uscals [1] "UnitedStates" "UnitedStates/LiborImpact" "UnitedStates/NYSE" [4] "UnitedStates/GovernmentBond" "UnitedStates/NERC" "UnitedStates/FederalReserve" [7] "UnitedStates/SOFR" > > yday <- Sys.Date() - 1 > yday [1] "2025-10-13" > > sapply(uscals, \(cal) { qlcal::setCalendar(cal); qlcal::isHoliday(yday) } ) UnitedStates UnitedStates/LiborImpact UnitedStates/NYSE TRUE TRUE FALSE UnitedStates/GovernmentBond UnitedStates/NERC UnitedStates/FederalReserve TRUE FALSE TRUE UnitedStates/SOFR TRUE >$
