Next and break statements in R Programming - Mini Project: Build & Apply

Using Next and Break Statements in R Loops

📖 Scenario: You are analyzing a list of daily temperatures. You want to skip days that are too cold and stop checking once you find a very hot day.

🎯 Goal: Build a program that loops through a list of temperatures, skips cold days below 10 degrees using next, and stops the loop when a temperature reaches or exceeds 30 degrees using break.

📋 What You'll Learn

Create a vector called temperatures with these exact values: 5, 12, 8, 15, 22, 30, 18

Create a variable called cold_threshold and set it to 10

Use a for loop with variable temp to go through temperatures

Inside the loop, use next to skip temperatures less than cold_threshold

Inside the loop, use break to stop if temp is 30 or more

Print each temperature that is processed (not skipped) before the break

💡 Why This Matters

🌍 Real World

Skipping and stopping loops early is useful when processing sensor data or filtering lists based on conditions.

💼 Career

Understanding control flow with next and break helps in data cleaning, automation scripts, and efficient programming.

1

Create the temperature vector

Create a vector called temperatures with these exact values: 5, 12, 8, 15, 22, 30, 18

R Programming

# Your code here

Need a hint?

Use the c() function to create a vector with the given numbers.

2

Set the cold temperature threshold

Create a variable called cold_threshold and set it to 10

R Programming

temperatures <- c(5, 12, 8, 15, 22, 30, 18)
# Your code here

Need a hint?

Just assign the number 10 to the variable cold_threshold.

3

Loop with next and break statements

Use a for loop with variable temp to go through temperatures. Inside the loop, use next to skip temperatures less than cold_threshold. Use break to stop the loop if temp is 30 or more.

R Programming

temperatures <- c(5, 12, 8, 15, 22, 30, 18)
cold_threshold <- 10
# Your code here

Need a hint?

Use for (temp in temperatures) to loop. Use if statements to check conditions and use next and break accordingly.

4

Print the processed temperatures

Run the program to print each temperature that is processed (not skipped) before the loop stops.

R Programming

temperatures = 30) {
    break
  }
  print(temp)
}
# Your code here

Need a hint?

The output should show only the temperatures 12, 15, and 22 each on its own line.
