How to Get Frequency Counts of Histogram in R (Example Code)

In this post, I’ll show how to extract the frequency counts of a histogram using the hist() function in the R programming language.

Example Data

data(iris)                        # Load example data for histogram
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

Example: Extracting Frequencies from hist() Function

hist(iris$Sepal.Length)$counts    # Getting count values
# [1]  5 27 27 30 31 18  6  6
