Congratulations to my student, Maggie Ma, for publishing her first #rstats package {ggincerta} on CRAN 🥳
Spatial uncertainty visualisation (bivariate, pixel, exceedance, glyph), like {Vizumap}, but fully integrated with ggplot2 -- a much simpler API with all the advantages of the ggplot2 system.

We are looking for #rstats community feedback on 3 new dplyr functions!
We're aiming to expand the `filter()` family:
- `filter()` to keep rows
- `filter_out()` to drop rows
- `when_any()` and `when_all()` as modifiers
