# Content

This repository has 14 activities: 

0) Very basics of R coding  

1) Data wrangling with dplyr and tidyr 

2) Formatting ggplots – faceting, scales, guides, and themes 

3) Design custom palette in R 

4) One-way ANOVA and the compact letter display 

5) What to do when ANOVA assumption fails 

6) Randomized block design ANOVA 

7) Multifactorial deign ANOVA and interactions 

8) Repeated measures ANOVA

9) Split field and nested experimental design

10) Correlation and linear regression

11) Polynomial curve fitting 

12) Logistic regression  

13) Proportions, contingency tables and enrichment 

The first three units focus on how to tidy data and make pretty plots.   

Units 4 - 9 focus on ANOVA and Tukey tests.   

Units 10 - 12 focus on regression. 

Formal math is kept to minimum. The series focus on basic concepts, interpretation and execution in R.   

Each unit builds upon the previous. After each unit, there is also an exercise. 

# Getting started
