Super-pleased to see that a couple of small Shiny app improvements I made this weekend correctly picked up on some source data changes today and automatically handled them. Pretty cool!
Having seen how easy it was to convert a couple of hobby projects to use {pins}, I’m now daydreaming about putting it at the center of an S3 data lake operation.
Sharing a quick tip that I’ve found useful while building with Shiny, recently: It’s handy to be able to save off the current state of a data set for bringing over to a scratch file. I made the download link appear only when running in my local environment. This way I can easily snapshot my in process data set for experimenting with visualization in my scratch file.
In ui.R:
if(interactive()) {
downloadLink("downloadData", "💾️ Download data set")
}
And in server.R:
output$downloadData <- downloadHandler(
filename = function() {
paste("shiny-export_", Sys.Date(), ".csv", sep="")
},
content = function(file) {
write.csv(globaldata$armor, file)
}
)
I had a good time this weekend coming up with a new way to visualize armor stat distribution in my Destiny 2 profiler tool. 🎮
Just learned of {httr2} (https://github.com/r-lib/httr2), a rewrite of R’s httr package, and am excited to try it out! The pipeable API looks like a nicely improved way to build complex requests.
I’ve had a nice afternoon working on my hobby R/Shiny project, a loadout finder for the game Destiny 2. These improvements make it a lot more flexible and informative: It can now optionally include armor that would otherwise be filtered out of configurations by the minimum stat threshold, and it will show current mods used in displayed loadouts.
I’m sure it poses some benefits for systematic parsing (and I’m certainly much more comfortable working in R and markdown, for what it’s worth) but Jupyter’s reliance on json for its file format seems like a big disadvantage for readability and portability.
This revision of ArmoreR is really turning into something I’m happy with and proud of. I’ve learned so much since the very first iteration of this about a year ago. It’s really fun and rewarding to come back to it with a bunch of new expertise and make it much better in all ways, including a new approach to dealing with such a large amount of information.

Sundays are for fixin' Shiny!
I spent a bunch of the weekend beginning a redesign of my ArmoreR project, which aims to be a Destiny 2 armor stats profiler built in R and Shiny. A year on from when I began it, I have a much better understanding of how a Shiny app works, and have also incorporated a proper, working oauth2 workflow into this revision (incorporating the things I figured out for my power level tracker). It’s really, really satisfying to be rebuilding it with all the things I’ve learned. I think the application is going to be so much better and less complicated than the first iteration. I still have a ways to go, and am happy with just how much I have transformed it with a year of learning and practice on other things.
