{ti} is now available on CRAN!
I've posted about this package before and with this latest update we finally have support for non-standard calendars
I gave up on non-standard calendars because of its complexity but thanks to @posit.co positron I was able to complete it!

dplyr 1.2.0 was released last week and since I use {dplyr} a lot in my work, I wanted to take some time to try some of the new functions.
This post provides some supplemental examples of the new functions, beyond what is provided in the new Posit materials.

Showed my Advanced GIS students Claude Code this week.
We built this map of code compliance violations in Fort Worth; heatmap giving way to points on zoom.
Used the ArcGIS SDK for JavaScript.
Took 10 minutes.
I believe in Jevons Paradox.
But we need to be teaching skills for 2026, not for 2016.

alright, for the "negative filtering of df in #rstats" illustration @sobchuk.bsky.social asked for subset() - so here it is! That should be all the basic bases covered, fingers crossed.
Note that it might look like dplyr::filter & subset are doing the same thing, but look at the rownumbers..
