Make a function that takes a df and a variable then produces a scatter plot of that variable vs cesd. Use it to plot multiple graphs of the first 6 numeric variables HELPrct. Hint: check out the extended example from 7.7
Day 29 Practice function writing in R
Day 28 Lab 6
Day 27: Bonus Project 2 day?
Making our own functions
Day 26: Iteration
Making our own functions
Day 25: Function refresher
Day 24: Project 2 work day
Day 23: Final Project: Website
Website work
Make a new private repo
Move all your website files to that repo
- Recall they are in your lab 1 folder.
Add your project 1 to your website.
You could just link it to the main page
Clean up your project

#| eval: False to not include the output of the code.
What more to do?
Day 22
