@joncounts I feel you with the install complications. Coming from #rstats, it's like "why doesn't this just work?!". I've been using #Positron for most of my R work recently and one nice feature is that it does a pretty good job at detecting all the various Pythons you have installed and let's you choose and switch between them. It *might* help smooth over the setup rough edges.

Positron's pros & cons. From improved workflow transparency, to growing debugging pains.

The truly important reason to try the #positron R/Python editor is that it can work in parallel with another R session open in #RStudio for a different project...
Also amazed by the #Pluto notebook for #Julia scientific work. One of its nice features is that the associated file is in text format and the code can be easily extracted. Not yet ready to switch from #ggplot to #VegaLite though.

Anyway here's that blogpost about using small shell wrappers for #pak and #renv and also #Positron and project management and whatnot for the #rstats crowd: https://blog.jemu.name/2025/03/r-usability-gimmicks/
blog.jemu.name · R Usability GimmicksThe other day I posted on Mastodon about shell script wrappers for common R commands.
And I thought I might as well flesh this out a little. So for context, I should not that in my everyday computing setup, I have configured by terminal iTerm2 as a hotkey window, meaning that whichever desktop space I’m on and whatever application is currently in focus, I just have to press F2 to pop down my terminal window.

positron.posit.coPositronA next-generation data science IDE
Nous sommes ravis de partager le #replay de notre récente Watch Party francophone qui a été dédiée à la posit::conf(2024) !
Au programme, deux présentations captivantes sur le nouvel #IDE #Positron développé par #Posit @Posit ainsi que sur #Quarto et tout son potentiel.
Chaima Boughanmi @chaimaboughanmi a également offert un retour d'#expérience inspirant sur sa participation à la conférence.
New blog post! I discuss the benefits of developing C/C++ code for R with the new Positron IDE (from @Posit) and provide some helpful functions to add to your R user profile to automate some current pain points away! See how you can use VSCode extensions to interactively debug and do cool things like inspect the size of structs (padding included!) while you program!

We at @Posit are hiring an engineer with experience in #Python developer or data science tooling to work on #Positron 
Take a look and let me know if you have any questions! #GetFediHired

"And when you crash R, you no longer crash the IDE!"
Challenge accepted and easily completed! I much prefer the RStudio bomb, though--far more personality.
Is there a good workflow for building/cleaning/installing local packages using Positron? The default package build in Positron uses `pak::local_install(upgrade = FALSE)`, which hides the compilation output (see below) and thus isn't very helpful when troubleshooting compilation failures.
I've been just working from the terminal with R CMD BUILD + R CMD INSTALL but it would be nicer to have a better way to do this in the IDE (that may already exist? Tell me!).
Feeling real SMORT after realizing that the #rstats #positron equivalent of rstudio "Switch Focus between Source/Console" command is just having the same key mapped to "Focus Console" and "Focus Editor" commands with different "when" conditions. Looks like a generalizable pattern for "toggle"-type commands, so I'm p excited to try making other kinds previously unavailable in rstudio.
(it only took me like 3 hours of digging around the source code to piece this together 
)

@yjunechoe @jennybryan said at #PositConf2024 that you can set up Positron to use RStudio-like keyboard shortcuts. I see that in Positron by going to Settings (the gear icon at bottom left) > Settings and then search for RStudio. You should then see a check box to "Enable RStudio key mappings for Positron"
Shouting into the void trying to set up #RStats #positron -- I'm looking for the following keyboard shortcut equivalents from RStudio:
Editor:
Go to Start of Line (cursorLineStart) Go to End of Line (cursorLineEnd)
- Switch Focus between Source/Console
Workbench: Move Focus to Console (workbench.action.positronConsole.focusConsole) Move Focus to Terminal (workbench.action.terminal.focus + see note in thread)
- Send Selection to Terminal
Any pointers greatly appreciated 
Looking for an open-source alternative to GitHub Copilot? Suggested during a #PositConf2024 Q&A: Continue.
On VSCode Marketplace: https://marketplace.visualstudio.com/items?itemName=Continue.continue
On the Open VSX Registry: https://open-vsx.org/extension/Continue/continue
It works with #VS Code, #JetBrains, @Posit 's #Positron and offers functionality such as explaining code sections, asking questions about your codebase, tab to autocomplete code suggestions, refactoring functions. Use commercial or local #llms
Fantastic #PositConf2024 talk by @PipingHotData on variable labels. I did not know about this long available feature in R 
but I now want to go and incorporate it into everything I do! Unfortunately it seems #VSCode does not display them in the table Viewer, however #Positron has an open issue, so I would assume it will get the feature soon. Even without Viewer support ATM, the benefits with ggplots, gt tables and being able to call str() are enough of a reason.
GitHub Copilot is not available for Positron, but other generative AI extensions are, including Continue with options for OpenAI, Claude, local models, and others
https://open-vsx.org/extension/Continue/continue
The Positron IDE data viewer is also a data explorer that can handle millions of rows and offers summarization and filters as well as viewing, @thomas_mock tells #PositConf2024. It works for data in both #Python and #R .
