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 >$

Yes! We see via the 'Deadlines' field from the return of `tools::CRAN_package_db()`. As maintainer I can now see which reverse dependencies "got email" (as the CRAN status pages shows).

I had done earlier (simpler) Armadillo transitions more manually, without 'Deadlines'. This is new for me too.

Yep! And while the `pushover` service costs a modest one-time fee, the similar `pushbullet` service is registration-only. So `RPushbullet` may be worth a consideration too for the same use cases. (And I am due a maintenance release...) #rstats

Depends on where you want the data. The `duckdb` csv reader runs circles even around `data.table::fread()` -- also from compressed files, multiple files, ....

But if you want to be in R I'd still go with`data.table::fread()`.

Many Chicagoans will head up to Milwaukee tomorrow for game 2 of the NLDS. Undoubtedly, some will take one of the 13-15 daily direct flights from O'Hare.

If we were a proper country with a modern rail system, there'd be no need for air travel between two major cities that are only 90 miles apart.

If memory serves I added this at some point on user request, so not sure how many years we had this but `anytime` does this by default (and `anytime()` does the same returning `POSIXct` instead of `Date`).

> anytime::anydate(c("2015", "2015-09", "2015-09-19"))
