Overview

This repo contains

• R scripts to make stats related .gifs
• statbiscuits worksheets (swots) that go hand in hand with courses I teach (source code here)
• source code for a simple RShiny application that allows students to explore the shapes of probability distributions: probable
• RShiny application introducing linear additive model with the Palmer penguins dataset. Link to the source code and link to more info about the data.
• Using aRt as an introduction to linear modelling inspired by Danielle Navarro's blog Notes from a data witch: Art, jasmines, and the water colours.

Feel free to fork and modify for your own use or just download the gifs :-)

Linear models

R script can be found here

Draw your own line of best fit

This works in conjunction with a Google Apps Script I made that allows students to draw their best line of fit online (mouseclicks only) and submit it to a shared Google Sheet. The R script then pulls all the start and end points of their drawn lines and creates a gif showing the distribution of all their estimates.

Code for this Google Script App can be found here and the exported line ends are available here

R side code can be found here
