Calculate Rank of the Values of a Vector in R Programming – rank() Function

Last Updated : 15 Jun, 2020

rank() function in R Language is used to return the sample ranks of the values of a vector. Equal values and missing values are handled in multiple ways.

Syntax: rank(x, na.last)

Parameters:
x: numeric, complex, character, and logical vector
na.last: Boolean Value to remove NAs

Example 1:

   # R program to print rank of a vector values 
  
# Creating a vector 
x <- c(2, 5, 3, 6, -4, NA, 7, Inf, 5) 
  
# Calling rank() function 
rank(x)

Output:

  [1] 2.0 4.5 3.0 6.0 1.0 9.0 7.0 8.0 4.5

Example 2:

   # R program to print rank of a vector values 
  
# Creating a vector 
x <- c(2, 5, 3, 6, -4, NA, 7, Inf, 5) 
  
# Calling rank() function 
rank(x) 
  
# Calling with NA removed 
rank(x, na.last = FALSE)

Output:

  [1] 2.0 4.5 3.0 6.0 1.0 9.0 7.0 8.0 4.5  [1] 3.0 5.5 4.0 7.0 2.0 1.0 8.0 9.0 5.5
