Good morning everyone,

Here’s the tutorial for this week’s write-up on the trapezoid of excellence. I’ve began to ask for some outside help for these coding tutorials to gauge if they’re good enough to follow. I’ve gotten some good feedback so you’ll notice this script has way more comments in it. I hope it inspires you to download R on your computer and give it a try! We will see. Please share anything I’ve inspired you to build in the comments, on twitter, or feel free to email me too. I love hearing about all of it, even if it’s still a work in progress. Thanks again for reading and talk soon - RC
