Overview

Welcome! This website contains a collection of graphs created using ggplot2 (and friends!).

Install ggplot2 using the code below:

Code

install.packages("ggplot2")
library(ggplot2)

Or you can install ggplot2 as part of the tidyverse:

Code

install.packages("tidyverse")
library(tidyverse)

The Data

To improve reproducibility, the majority of the graphs are built using the palmerpenguins::penguins data.

…so…many…PENGUINS!

Artwork by @allison_horst

Code

install.packages("palmerpenguins")
library(palmerpenguins)

Some of the graphs use datasets from the fivethirtyeight package.

Code

install.packages("fivethirtyeight")
library(fivethirtyeight)

To view a table of available datasets in the fivethirtyeight package, view the Data Frame Name and Article Title columns in the datasets_master table:

A few of the graphs are built using the ggplot2movies::movies data.

Code

install.packages("ggplot2movies")
library(ggplot2movies)

The Graphs

The gallery follows a Rule of Least Power Principle, in the sense that “a language with a straightforward syntax may be easier to analyze than an otherwise equivalent one with more complex structure.”

In other words, assuming the reader has some understanding of R and the tidyverse, the code for each graph is meant to be read and understood without having to run it.

Graph Categories

Graphs have been categorized into the following types:

• Univariate graphs
  
• Amounts
• Proportions
  
• Comparing Distributions
  
• Relationships

Some graphs would justifiably belong in more than one category, and wherever this is the case, I’ve tried to include links to other uses in the notes.

Code style & structure

Each graph has, at minimum, the same two sections and four tabs:

1. Packages and Data
   • Code for installing development version of packages (if necessary) for graphs and data
     
   • Any steps used to create (i.e., manipulate and prepare) the data for the graph
     
2. Code and Graph
   • Code to build the labels and graph layers
     • Graph labels have the labs_ prefix
       
     • Graph layers have a ggp2_ prefix

DATA:

Description of data

Code

df <- tibble::tibble(X = sample(x = 1:100, 10, FALSE),
                     Y = rlnorm(10, 1, 3))

Code for creating graph

Code

# labels
labs_graph <- ggplot2::labs(title = "Title", 
                            subtitle = "subtitle", 
                            x = "X", y = "Y")
# layers
ggp2_graph <- ggplot2::ggplot(data = df, 
    mapping = aes(x = X, y = Y)) + 
    ggplot2::geom_blank()
# graph
ggp2_graph + 
    labs_graph

Code Style:

I’ve attempted to balance brevity and clarity, but with the assumption that its best to err on the latter. I’ve also followed the general principle that if a graph can be easily built using one of ggplot2 ’s geom_* functions, that method is shown first.
