Quotes of the Week

Made a little something to help students quickly convert between wide and long data for my (no-code) viz class. Helpful for when Datawrapper or Rawgraphs insist on a particular format for certain chart types. Built with #svelte and #rstats using webR!pivotteer.netlify.app

💯. R is so amazing, not only the language but the community. I have not found the same breadth of documentation and teaching materials elsewhere. With vignettes and tutorials routinely bridging domain specific science, stats and math concepts, and program implementation.
