Pix all the right boxes The {pixeltrix} package—which I’ve written about before—lets you open an interactive R plot that you can click to turn ‘pixels’ on and off. I created it for one purpose: to quickly create simple, blocky sprites for my {tamRgo} package, which lets you keep a persistent cyberpet on your computer (yes, really). https://www.rostrum.blog/2022/09/24/pixeltrix/ Sat, 24 Sep 2022 00:00:00 +0000 https://www.rostrum.blog/2022/09/24/pixeltrix/ tl;dr I’ve written {pixeltrix}, an R package that lets you select ‘pixels’ interactively from a plot window and returns your final image as a matrix. You could use it to design sprites, for example. Pixel perfect I’ve written before about creating very simple pixel art in R. To create a sprite of Link from The Legend of Zelda I had to write out by hand a vector that encoded its pixel values.
