R Program to Find Minimum and Maximum Values

Introduction

Finding the minimum and maximum values in a dataset is a fundamental task in data analysis. In R, you can easily determine these values using built-in functions. This guide will walk you through writing an R program that finds and displays the minimum and maximum values in a numeric vector.

Problem Statement

Create an R program that:

• Creates a numeric vector with a series of values.
• Finds the minimum value in the vector.
• Finds the maximum value in the vector.
• Displays both the minimum and maximum values.

Example:

• Input: A vector with elements c(10, 25, 3, 47, 15)
• Output: Minimum value: 3, Maximum value: 47

Solution Steps

1. Create a Numeric Vector: Use the c() function to create a vector with a sequence of numeric values.
2. Find the Minimum Value: Use the min() function to find the minimum value in the vector.
3. Find the Maximum Value: Use the max() function to find the maximum value in the vector.
4. Display the Minimum and Maximum Values: Use the print() function to display the minimum and maximum values.

R Program

# R Program to Find Minimum and Maximum Values
# Author: Ramesh Fadatare

# Step 1: Create a numeric vector with a series of values
my_vector <- c(10, 25, 3, 47, 15)

# Step 2: Find the minimum value in the vector
min_value <- min(my_vector)

# Step 3: Find the maximum value in the vector
max_value <- max(my_vector)

# Step 4: Display the minimum and maximum values
print(paste("Minimum value:", min_value))
print(paste("Maximum value:", max_value))

Explanation

Step 1: Create a Numeric Vector

• The c() function is used to create a numeric vector with the elements c(10, 25, 3, 47, 15).

Step 2: Find the Minimum Value

• The min() function is used to find the minimum value in the vector, which is stored in the min_value variable.

Step 3: Find the Maximum Value

• The max() function is used to find the maximum value in the vector, which is stored in the max_value variable.

Step 4: Display the Minimum and Maximum Values

• The print() function is used to display the minimum and maximum values with descriptive messages.

Output Example

Example:

[1] "Minimum value: 3"
[1] "Maximum value: 47"

Conclusion

This R program demonstrates how to find the minimum and maximum values in a numeric vector using the min() and max() functions. It covers basic operations such as vector creation, finding extreme values, and displaying results, making it a valuable example for beginners learning R programming. Understanding how to identify these values is crucial for data analysis and manipulation.
