In this series of videos, we are going to perform a complete analysis of a two-factor factorial design.
We are going to cover the following steps :
Video tutorial 1 ( • Two-Way ANOVA with R - Analysis of Variance ):
build a simple plot for data visualisation;
perform the analysis of variance;
Video tutorial 2:
create a table with the mean and standard deviation of each treatment;
compare the means by Tukey’s test;
use the compact letter display to indicate significant differences;
Video tutorial 3 ( • Publication-Quality Barplots for Two Facto... ):
build a high-quality publication-grade bar plot,
Video tutorial 4 ( • Publication-Quality Barplots for Two Facto... ):
build a high-quality publication-grade scatter plot.
Packages: ggplot2, multcompView, dplyr
