Get the Minimum element of an Object in R Programming – min() Function

min() function

min() Function in R Language

The min() function in R is used to determine the smallest value within an object. This object can be a vector, list, matrix, data frame, or other types.

Syntax

min(object, na.rm)

Parameters

• object: A vector, matrix, list, data frame, etc., containing the elements.
• na.rm: A logical parameter; if TRUE, it removes NA values before computing the minimum.

Example 1: Finding the Minimum Value in Vectors

# R program to demonstrate the min() function

# Creating vectors
vec1 <- c(3, 7, 1, 5, 9)
vec2 <- c(10, NA, 2, 6, 15)

# Applying min() function
min(vec1)
min(vec2, na.rm = FALSE)
min(vec2, na.rm = TRUE)

Output:

[1] 1
[1] NA
[1] 2

Example 2: Finding the Minimum Value in a Matrix

# R program to demonstrate the min() function

# Creating a matrix
mat <- matrix(10:21, nrow = 3, byrow = TRUE)
print(mat)

# Applying min() function
min(mat)

Output:

[,1] [,2] [,3] [,4]
[1,]   10   11   12   13
[2,]   14   15   16   17
[3,]   18   19   20   21
