Animated graphics: intro to ggplot2 with gganimate

Eco-Data-Science session (UCSB Collaboratory, January 15^th, 2019)

Prepared by Allison Horst

In this eco-data-sci session, we'll use simple examples to refresh ggplot2 skills, learn some basics of gganimate with ggplot2, and explore a few other useful ggplot tools.

Included:

• Animated scatterplots
• Animated line plots
• Animated ridge plots (ggplot2 + ggridges + gganimate)
• Easing + tweening options (ease_aes and enter/exit)
• 4 transition types: transition_states, transition_layers, transition_manual, transition_reveal
• Repulsive text labels (geom_text_repel)

Required packages:

• tidyverse
• ggridges
• gganimate
• ggrepel

Install gganimate development version from github:

install.packages('devtools')
devtools::install_github('thomasp85/gganimate')
