R Console and script files in R Programming - Mini Project: Build & Apply

R Console and Script Files

📖 Scenario: You are learning how to use R for data analysis. You will practice writing commands in the R Console and saving them in script files for reuse.

🎯 Goal: Create a simple R script that assigns values to variables, performs a calculation, and prints the result. This will help you understand how to work with the R Console and script files.

📋 What You'll Learn

Create variables with exact names and values

Use a helper variable for calculation

Write a calculation using the variables

Print the final result exactly

💡 Why This Matters

🌍 Real World

Calculating areas and other measurements is common in data analysis, statistics, and scientific research using R.

💼 Career

Knowing how to write and run R scripts is essential for data scientists, statisticians, and researchers who use R for data processing and analysis.

1

Create variables in R

Create two variables called length and width with values 7 and 5 respectively.

R Programming

# Create variables length and width with values 7 and 5
# Your code here

Need a hint?

Use the assignment operator <- to assign values to variables.

2

Add a helper variable

Create a variable called area and set it to 0 as a starting point.

R Programming

length <- 7
width <- 5
# Create variable area and set it to 0
# Your code here

Need a hint?

Initialize area with 0 before calculating.

3

Calculate the area

Calculate the area of a rectangle by multiplying length and width, and assign the result to area.

R Programming

length <- 7
width <- 5
area <- 0
# Calculate area by multiplying length and width
# Your code here

Need a hint?

Use the multiplication operator * to calculate the area.

4

Print the result

Use the print() function to display the value of area.

R Programming

length <- 7
width <- 5
area <- 0
area <- length * width
# Print the area
# Your code here

Need a hint?

Use print(area) to show the result in the console.
