Get the Minimum and Maximum element of a Vector in R Programming – range() Function

Get the Minimum and Maximum element of a Vector in R Programming in detail

The range() function in R is used to determine the smallest (minimum) and largest (maximum) values in a given vector.

Syntax:

range(x, na.rm = FALSE, finite = FALSE)

Parameters

• x: A numeric vector whose minimum and maximum values are to be calculated.
• na.rm: Logical (Boolean) value indicating whether to exclude NA values from the computation. Default is FALSE.
• finite: Logical value to specify whether to exclude non-finite elements (like Inf and -Inf). Default is FALSE.

Examples of range() Function in R

Example 1: Finding the Minimum and Maximum of a Numeric Vector

# Define a numeric vector
vec <- c(10, 4, 7, 15, 2, 6)

# Compute the range
range(vec)

Output:

[1]  2 15

Example 2: Handling NA and Non-Finite Values

# Define a numeric vector with NA and non-finite values
vec <- c(10, 4, NA, Inf, 7, -Inf, 2)

# Compute the range without additional arguments
range(vec)

# Compute the range, ignoring NA values
range(vec, na.rm = TRUE)

# Compute the range, ignoring NA and non-finite values
range(vec, na.rm = TRUE, finite = TRUE)

Output:

[1] NA NA
[1]  -Inf   Inf
[1]  2 10
