This gives a fantastic framing of how to think about reproducibility (it's a spectrum) and how to use renv with intention. Highly recommend, even if you're not using renv, to get a better understanding of how to live in peace as R and package versions advance 🕊️ #rstats
The recording of my #rstats posit::conf talk ✨ practical {renv}✨ is available! 🎉
I created this talk for frustrated {renv} users 🫠 and potential {renv} users🤩

My keynote about data science tools at posit::conf is now online! I originally meant it to be a talk about Positron, but as I was writing it, it took a left turn through the history of RStudio and into the philosophy of tool design & how to build stuff for people.

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

Will definitely include this example in my next talk on how to name files!
✅ Full marks for "make it easy to guess what the heck something is, based on it name".

Genuinely delighted to download a PhD thesis from a university repository where the author has neglected to remove the words "BITCH THIS IS YOUR THESIS" from the filename.

I'm excited to share a new version of the Air formatter for #rstats, with support for tabular formatting! Super useful with `tibble::tribble()` calls or `data.table::fcase()`.
It's currently experimental as we're looking to get feedback on the feature, so please let us know what you think.

BTW this "Frequency Reduces Difficulty" post from @martinfowler.com is the origin of the mantra "if it hurts, do it more often" (at least, it's where I learned it). It's amazing how broadly this applies.

bliki: Frequency Reduces Difficulty
"If it hurts - do it more often". Good advice if the amount of pain raises exponentially with the time between actions, such as for integrating software.

I bet the whole reason he's thinking about this is that I was complaining to him (to everyone, really) about the pain of using Windows full-time while my macbook's logic board gets replaced. And he brought out the house words "if it hurts, do it more often!"
Three phrases that capture some of the tidyverse team culture:
Everybody takes out the trash
We suffer so users don’t have to
If it hurts, do it more often
Everybody takes out the trash
We suffer so users don’t have to
If it hurts, do it more often
