How to Plot a Cumulative Histogram in R (Example Code)
In this R post you’ll learn how to draw the cumulative sum of a vector in a histogram.
Setting up the Example
data(iris) # Example data head(iris) # Sepal.Length Sepal.Width Petal.Length Petal.Width Species # 1 5.1 3.5 1.4 0.2 setosa # 2 4.9 3.0 1.4 0.2 setosa # 3 4.7 3.2 1.3 0.2 setosa # 4 4.6 3.1 1.5 0.2 setosa # 5 5.0 3.6 1.4 0.2 setosa # 6 5.4 3.9 1.7 0.4 setosa |
data(iris) # Example data head(iris) # Sepal.Length Sepal.Width Petal.Length Petal.Width Species # 1 5.1 3.5 1.4 0.2 setosa # 2 4.9 3.0 1.4 0.2 setosa # 3 4.7 3.2 1.3 0.2 setosa # 4 4.6 3.1 1.5 0.2 setosa # 5 5.0 3.6 1.4 0.2 setosa # 6 5.4 3.9 1.7 0.4 setosa
install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2 package |
install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2 package
ggplot(iris, # ggplot2 histogram without cumulative values aes(x = Sepal.Length)) + geom_histogram() |
ggplot(iris, # ggplot2 histogram without cumulative values aes(x = Sepal.Length)) + geom_histogram()
Example: Draw Cumulative Histogram Using ggplot2 Package
ggplot(iris, # ggplot2 histogram with cumulative values aes(x = Sepal.Length)) + geom_histogram(aes(y = cumsum(..count..))) |
ggplot(iris, # ggplot2 histogram with cumulative values aes(x = Sepal.Length)) + geom_histogram(aes(y = cumsum(..count..)))
