I’ve had a really nice hobby R coding weekend, learning to use {gganimate} to make plots like this. I’ve been re-tooling all my old piles of fish scripts that I’ve used to gather my Destiny data from the game’s API. Now I have a useful pair of quarto notebooks that retrieve data using parallel processing and produce this kind of output. I’m super enthused by what I’ve learned!

Had a pretty good hobby coding weekend learning how to use purrr::pluck() to get specific nested fields from piles of json data rather than blowing out the whole series of nested lists.

I learned today that one of the magical things pandoc can do under the hood for Quarto is use a Powerpoint template to render slides. I can work in RStudio to make slides in my company’s style; this is amazing!

(Footnote: This assumes a template that uses at least some standard powerpoint slide notation, which my company’s official templates do … not quite do. But a little bit of revision of the slide master got me there!)

Got nginx running on my MacBook today, as part of building some working-with-APIs-infrastructure for a small tutorial I want to write on working with oauth in Shiny. Good step!

I’m officially on vacation, but there’s so much that I want to “bring back” to work with me from this week’s rstudio::conf. Looking forward to one more day with this community of folks doing and learning things.

Two windows from the RStudio profvis tool, showing the times of several procesess. The second window shows the same process being completed dramatically more quickly than the first.

I used the RStudio tool profvis this weekend to find speed improvement opportunities in Armorer. I suspected that I could rewrite a big operation that calculates the maximum of many columns across several thousand rows. Holy smokes: Using matrixStats::rowMaxs cuts processing time by an amazing amount!

I finished a big update to Armorer this week, to enable inclusion of subclass fragments in stat calculations. I learned a ton with this release and laid good groundwork for additional mod management. I’m pretty pleased!

I’m happy to have improved some R code today using group_split, replacing my prior method of cycling through a data frame to build several new subsets. I’m not sure it’s more efficient given the size of the data set, but it sure reads more nicely.
