Overview

The rep function in R replicates the values in a given vector.

Syntax

rep.int(x, times)
The syntax for the rep() function in R

Parameter value

The rep() function takes the following parameter values:

  • x : This is the input vector whose values are to be replicated.
  • times: This specifies the number of times the value of x has been replicated.

Return value

The rep() function returns an object of the same type as the input vector x.

Example

# A code to illustrate the rep() function in R



# creating a vector object

a <- 1:5



# replicating the values in a by 2 times

b <- rep(a, 2)



b

Explanation

  • Line 4: We create a vector object, a.
  • Line 7: We use the rep() function to create a replicate of the values of a. The result is assigned to a variable, b.
  • Line 9: We print the value of b.
