I love how excited June clearly is about this! You can see him talk a lot more about this over in the ggplot2 book club from @R4DScommunity, see r4ds.io/youtube #RStudioConf2022 #RStudioConf #RStats

CRAN.R-project.org/package=ggtrace is his package for dealing with this stuff without it being scary. #RStudioConf2022 #RStudioConf #RStats
ggtrace lets us capture data frames at each step of a plot to make more complex thoughts. Neat! #RStudioConf2022 #RStudioConf #RStats

#RStudioConf2022 Day 2 🧵 of 🧵! I'm looking back at my notes to see what I learned yesterday. See Day 1 over here:
#RStudioConf #RStats
Things started off with a bang with @minebocek and @juliesquid officially introducing @quarto_pub
#RStudioConf2022 #RStudioConf #RStats #PyData
I've been skeptical ("Isn't this just RMarkdown renamed so 🐍 people aren't afraid of it?") but making a v2 of something lets you make it better. @quarto_pub looks like it's really great! Claim your quarto.pub name! #RStudioConf2022 #RStudioConf #RStats #PyData

Now that #RStudioConf2022 is over and I've had some time to process, it's time for a 🧵 to look back and summarize my copious notes. Hopefully this can be useful to someone other than just me! #RStudioConf #RStats #PyData
Before the conf proper, I TAed the 🔮 {tidymodels} workshop. Because @RStudio / #Posit are who they are, all workshop materials are free and open via github.com/rstudio/rstudi… (github.com/rstudio-conf-2… in case that link ever breaks) #RStudioConf2022 #RStudioConf #RStats
#RStudioConf2022 proper kicked off with a pre-keynote announcement from @fly_upside_down & @hadleywickham. As you've probably heard, @RStudio is now #Posit 💭. My thread (with old hashtag):

Yay! Time for @coolbutuseless! #RStudioConf2022 #RStudioConf #RStats Mike starting his speech.

Now @brshallo parsing R files! #RStudioConf2022 #RStudioConf #RStats Bryan on stage.
Ha, yes, I've also been known to obsessively follow projects, Bryan! When I heard the tune 📦was coming but github.com/tidymodels/tune was a 404, I set up something to check it every couple hours then beepr::beep when it wasn't a 404 anymore 😁 #RStudioConf2022 #RStudioConf #RStats Eye emoji watching various R books and TidyTuesday.

Up next: @GregSwinehart with Designing for people is hard. He made the shiny logo! It was original a baseball shirt (thus the font)! #RStudioConf2022 #RStudioConf #RStats Greg on stage with the shiny logo.
What's it like to be a ui designer? It is awful. Also it is awesome. It just depends if things are working and/or pretty! #RStudioConf2022 #RStudioConf #RStats I hate it A heart with text "I love it"
"how can we make shiny apps look better?" #noHTML #noCSS
