1 Goal

The goal of this tutorial is to show a sample of complete themes contained in the ggthemes library. For default themes check the default themes tutorial.

2 Drawing with ggplot

# First we load the libraries
library(ggplot2)
library(ggthemes)

# In this example we will use the open repository of plants classification Iris. 
data("iris")
str(iris)
## 'data.frame':    150 obs. of  5 variables:
##  $ Sepal.Length: num  5.1 4.9 4.7 4.6 5 5.4 4.6 5 4.4 4.9 ...
##  $ Sepal.Width : num  3.5 3 3.2 3.1 3.6 3.9 3.4 3.4 2.9 3.1 ...
##  $ Petal.Length: num  1.4 1.4 1.3 1.5 1.4 1.7 1.4 1.5 1.4 1.5 ...
##  $ Petal.Width : num  0.2 0.2 0.2 0.2 0.2 0.4 0.3 0.2 0.2 0.1 ...
##  $ Species     : Factor w/ 3 levels "setosa","versicolor",..: 1 1 1 1 1 1 1 1 1 1 ...
# Let's plot the petal length vs petal width
ggplot() + geom_point(data = iris, aes(x = Petal.Width, y = Petal.Length,color = Species))

3 ggthemes

3.1 Calc theme

# Theme similar to the default settings of LibreOffice Calc 
ggplot() + geom_point(data = iris, aes(x = Petal.Width, y = Petal.Length,color = Species)) + theme_calc()

3.2 The economist theme

# Style plots similar to those in The Economist
ggplot() + geom_point(data = iris, aes(x = Petal.Width, y = Petal.Length,color = Species)) + 
  theme_economist()

3.3 The economist white theme

# Style plots similar to those in The Economist
ggplot() + geom_point(data = iris, aes(x = Petal.Width, y = Petal.Length,color = Species)) + theme_economist_white()

3.4 Few theme

# Theme based on the rules and examples in Stephen Few, "Practical rules for using colors in charts"
ggplot() + geom_point(data = iris, aes(x = Petal.Width, y = Petal.Length,color = Species)) + theme_few()

3.5 Solarized theme

# Check http://ethanschoonover.com/solarized for a description of the solarized palette
ggplot() + geom_point(data = iris, aes(x = Petal.Width, y = Petal.Length,color = Species)) + theme_solarized()

3.6 gdocs theme

# Theme similar to the default used in google docs
ggplot() + geom_point(data = iris, aes(x = Petal.Width, y = Petal.Length,color = Species)) + theme_gdocs()

4 Complete list of themes in the package

# For the complete list of themes in the package check
ls("package:ggthemes")[grepl("theme_", ls("package:ggthemes"))]
##  [1] "theme_base"            "theme_calc"           
##  [3] "theme_economist"       "theme_economist_white"
##  [5] "theme_excel"           "theme_few"            
##  [7] "theme_fivethirtyeight" "theme_foundation"     
##  [9] "theme_gdocs"           "theme_hc"             
## [11] "theme_igray"           "theme_map"            
## [13] "theme_pander"          "theme_par"            
## [15] "theme_solarized"       "theme_solarized_2"    
## [17] "theme_solid"           "theme_stata"          
## [19] "theme_tufte"           "theme_wsj"
