max() function in detail

max() Function in R Language
The max() function in R is used to identify the largest element in a given object. This object can be a vector, list, matrix, data frame, etc.

Syntax

max(object, na.rm)

Parameters

• object: Any R object such as a vector, matrix, list, or data frame.
• na.rm: A logical value (TRUE or FALSE) that determines whether to ignore NA values.

Example 1: Finding the Maximum Element in Vectors

# Creating vectors
vector1 <- c(12, 25, 8, 14, 19)
vector2 <- c(5, NA, 17, 4, 10)

# Finding the maximum element
max(vector1)               # Without NA
max(vector2, na.rm = FALSE) # Includes NA
max(vector2, na.rm = TRUE)  # Excludes NA

Output:

[1] 25
[1] NA
[1] 17

Example 2: Finding the Maximum Element in a Matrix

# Creating a matrix
matrix_data <- matrix(1:12, nrow = 3, ncol = 4)
print(matrix_data)

# Finding the maximum element
max(matrix_data)

Output:

[,1] [,2] [,3] [,4]
[1,]    1    4    7   10
[2,]    2    5    8   11
[3,]    3    6    9   12
