Lol. Calling our future overlords clankers out in the open? Bold move. And an interesting project!

Seems to be back up now.

SNOTEL: Anyone else unable to access either the Rest or SOAP APIs or is it just my stuff? Anyone know what's going on? Site said they were down for maintenance last night and now this.

But also, be angrier with those that control the totality of the government at the moment.

Jason Mercer @wetlandscapes.bsky.social · 23d

I noticed opencode doesn't have a default LSP for #rstats. I'm a bit confused as to what custom LSP should be used with opencode as there seems to be air, Ark, and languageserver. Anyone have thoughts?

📚Coming soon: Chapters from our open-access book "Hello Data Science," based on our intro courses across three institutions!

📦 Today, we’re releasing the early version of the #rstats package with datasets. Find it on GitHub (on its way to CRAN): github.com/hellodata-sc...

Positron is building up dev container support! This is big! github.com/posit-dev/po... #rstats #python

Support for development containers · Issue #4691 · posit-dev/positron

Ah, didn't realize pins worked with python, too. Was thinking something a bit more language agnostic, but good to know this works for the two most common languages I use

Jason Mercer @wetlandscapes.bsky.social · Nov 24

What are your data science strategies for managing medium to big data in the context of version controlled code? Ideally in a way that is agnostic to OS and language and is fairly cheap and can be hosted on prem or in the cloud. DVC? Symbolic links? Something else? #rstats #python #julialang

Jason Mercer @wetlandscapes.bsky.social · Nov 16

For the project I'm currently working on, I'm just gonna go full {pak}. Definitely gonna checkout {rix} and {rv} in the future, though

Jason Mercer @wetlandscapes.bsky.social · Nov 16

The community in this thread is one of the reasons I really like #rstats. So many genuine and helpful people.

Jason Mercer @wetlandscapes.bsky.social · Nov 16

Getting {renv} and {pak} to play nicely together in a docker container is a nightmare #rstats

Jason Mercer @wetlandscapes.bsky.social · Nov 16

Oh, so like older than what PPM archives? Yeah, that's rough because then it's just local caching, to the degree that's possible

Jason Mercer @wetlandscapes.bsky.social · Nov 16

Do you use the posit package manager (PPM) repo? I find using their pre-compilied binaries along with caching from BuildKit drastically increases my iteration speed.

Jason Mercer @wetlandscapes.bsky.social · Nov 16

Yesh. That might even be part of the issue. No matter what I do, renv and pak generate a conflict during the build phase due to some mismatch in environment variables, library locations, etc. Sad trombone

Jason Mercer @wetlandscapes.bsky.social · Nov 16

That's great, because I'm losing my mind trying to figure this out. May have to use it on another project, but good to have it in the toolbox

This has me cackling. Thank you @hadley.nz

Hadley Wickham @hadley.nz · Nov 6

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp....

genzplyr is dplyr, but bussin fr fr no cap.

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

Read more and leave feedback here:
github.com/tidyverse/ti...

Example of using `filter_out()` on the `penguins` dataset, showing how it is much easier than `filter()`, especially with `NA`s

What about great_tables, which is the python version of gt: posit-dev.github.io/great-tables.... Full disclosure, never used tinytables, so I may be off base

Looking to use Quarto inside Positron, our new IDE for data science? We’ve released a video and guide for getting started.

Positron makes Quarto easy: Quarto is pre-installed, you get dedicated buttons for tasks like "Preview," and full coding support.

Are you?

📢 PSA: The R-Forge server is under attack from hackers and hence web access (e.g., for package installation) is currently down. #rstats

The team at WU Wien is working on it. I'll report here when it is back up again.
