Return the Index of the First Minimum Value of a Numeric Vector in R Programming – which.min() Function

which.min() function in R Language is used to return the location of the first minimum value in the Numeric Vector.

Syntax: which.min(x)

Parameters:
x: Numeric Vector

Example 1:

# R program to find index of 
# first minimum value 

# Creating a vector 

x <- c(2, 3, 4, 5, 1, 2, 3, 1, 2) 

# Calling which.min() function 

which.min(x) 

# Printing minimum value 

x[which.min(x)]

Output:

[1] 5
[1] 1

Example 2:

# R program to find index of 
# first minimum value 

# Calling pre-defined dataset 
BOD$demand 

# Calling which.min() function 

which.min(BOD$demand) 

# Printing minimum value 

BOD$demand[which.min(BOD$demand)]

Output:

[1] 8.3 10.3 19.0 16.0 15.6 19.8
[1] 1
[1] 8.3
