Explain Head and Tail function in R?

tail() function in R language is used to get the last parts of a vector, matrix, table, data frame or function.

Syntax: tail(x, n)

Parameters:
x: specified data types
n: number of row need to be printed

Example:

# R program to illustrate
# tail function
  
# Calling the tail() function to 
# get the last iris demo dataset
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
147          6.3         2.5          5.0         1.9 virginica
148          6.5         3.0          5.2         2.0 virginica
149          6.2         3.4          5.4         2.3 virginica
150          5.9         3.0          5.1         1.8 virginica

head() function in R language is used to get the first parts of a vector, matrix, table, data frame or function.
