tail(iris)

Output:

    Sepal.Length Sepal.Width Petal.Length Petal.Width   Species
145          6.7         3.3          5.7         2.5 virginica
146          6.7         3.0          5.2         2.3 virginica

Example 2:

# R program to illustrate
# tail function

# Calling the tail() function to
# get the last iris demo dataset
# in 4 rows
tail(iris, 4)

Output:

    Sepal.Length Sepal.Width Petal.Length Petal.Width   Species
