Put another way, what integer perimeter less than or equal to 1000 has the most Pythagorean triples? /blog/p5-in-r/ Fri, 23 Mar 2018 00:00:00 +0000 /blog/p5-in-r/ p5.js is a version of Processing built natively in JavaScript. It’s really, really awesome. Sean Kross wrote R bindings for p5.js in his p5 package so it can be written and R and published as an htmlwidget. This is a little exploration of how it works. library(p5) # runs once at start setup_ <- setup() %>% createCanvas(500, 500) %>% noStroke() # reruns every frame draw_ <- draw() %>% background('#888') %>% fill(rgb(1, 1, 1, 0.
