An introduction to cowplot

By Meghan Hall

Added Sat Dec 11, 2021

What is this?

Excerpt from site: “This week’s #TidyTuesday data set is all about lemurs (with data from the Duke Lemur Center), so I figured I would stick with the animal theme and discuss a few functions from Claus Wilke’s cowplot package, which is my personal favorite package for arranging plots made in R”.

Data Visualization Course

By Andrew Heiss

What is this?

Excerpt from site: In this class, you’ll learn how to use industry-standard graphic and data design techniques to create beautiful, understandable visualizations and uncover truth in data.

By the end of this course, you will become (1) literate in data and graphic design principles, and (2) an ethical data communicator, by producing beautiful, powerful, and clear visualizations of your own data.

Data Visualization for Educational Data Science💯

Added Thu Dec 31st, 2020

What is this?

Welcome to the second course in the Educational Data Science Specialization taught at the University of Oregon through the College of Education. This course will be taught through R, a free and open-source statistical computing environment, and will provide students with the foundational principles and practice of data visualization, particularly as applied to scientific and technical data. We will have weekly lectures, covering a wide variety of topics including human perception, color theory, and principles of visual design. We will also cover mediums for communication across diverse audiences with an emphasis on different web applications. Weekly hands-on laboratory sessions provide students the opportunity to put the lecture material into practice.

Data visualisation using R, for researchers who don’t use R💯

Added Fri Feb 18th, 2022

What is this?

Excerpt from site: In this tutorial, we provide a practical introduction to data visualisation using R, specifically aimed at researchers who have little to no prior experience of using R. First we detail the rationale for using R for data visualisation and introduce the “grammar of graphics” that underlies data visualisation using the ggplot2 package. The tutorial then walks the reader through how to replicate plots that are commonly available in point-and-click software such as histograms and boxplots, as well as showing how the code for these “basic” plots can be easily extended to less commonly available options such as violin-boxplots.

First steps in spatial handling and visualization

By Sébastien Rochette, Dorris Scott, & Jakub Nowosad

What is this?

Excerpt from tutorial: The tutorial is designed for R users from a variety of fields who are interested in working with spatial data and creating maps with R. No knowledge of cartography is required. Prior knowledge of (non-spatial) graphic making and data handling with the {tidyverse} in R is recommended.

ggplot Wizardry: My Favorite Tricks and Secrets for Beautiful Plots in R

What is this?

Excerpt from site: In this talk, I present my favorite tips and tricks with regard to the ggplot2 package, a library for plotting in the programming language R. I will cover functions that are helpful but many may not be aware of as well as a collection of interesting functions from a large range of extension packages. The talk is intended for people who already know how to code in R and ggplot2. However, I am going to cover a diverse collection of tips so I hope everyone can pick something helpful independent from their level of expertise.

How to Increase Legend Key Size in ggplot2

By datavizpyr

Added Fri Apr 14th, 2023

What is this?

Excerpt from article: In this tutorial, we will learn how to increase the color legend’s point (or legend key) size in ggplot2. Often when you make a plot with multiple groups and large number of data points, the legend key for the color variable are small and can be not legible in the plot.

Here we will see examples of increasing the point size of the legend in a scatter plot using guides() function in ggplot2.

Modify components of a theme

What is this?

Excerpt from site: Themes are a powerful way to customize the non-data components of your plots: i.e. titles, labels, fonts, background, gridlines, and legends. Themes can be used to give plots a consistent customized look. Modify a single plot’s theme using theme(); see theme_update() if you want modify the active theme, to affect all subsequent plots. Use the themes available in complete themes if you would like to use a complete theme such as theme_bw(), theme_minimal(), and more.
