Access Particular Element of Data Frame in R (2 Examples)

In this post you’ll learn how to return particular data frame elements in the R programming language.

Construction of Example Data

data(iris)                     # Using iris as 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

Example 1: Selecting Specific Data Frame Element Using Row Index & Column Index

iris[4, 3]                     # Returning single element
# [1] 1.5

Example 2: Selecting Specific Data Frame Element Using Row Index & Column Name

iris[4, "Petal.Length"]        # Returning single element
# [1] 1.5
