Inline R code in R Programming - Mini Project: Build & Apply

Using Inline R Code in R Markdown

📖 Scenario: You are preparing a simple R Markdown report to show some basic calculations inline with your text. This helps make your report dynamic and clear.

🎯 Goal: Create an R Markdown snippet that uses inline R code to display the result of a calculation inside a sentence.

📋 What You'll Learn

Create a numeric variable called num_apples with the value 5

Create a numeric variable called num_oranges with the value 3

Create a variable called total_fruits that sums num_apples and num_oranges

Write an R Markdown sentence that uses inline R code to show the value of total_fruits

💡 Why This Matters

🌍 Real World

Inline R code is used in R Markdown reports to show dynamic results inside text, making reports clear and automatically updated.

💼 Career

Data analysts and scientists use inline R code to create professional reports that update calculations automatically when data changes.

1

Create variables for fruit counts

Create a numeric variable called num_apples and set it to 5. Also create a numeric variable called num_oranges and set it to 3.

R Programming

# Create variables num_apples and num_oranges
# Your code here

Need a hint?

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

2

Calculate total fruits

Create a variable called total_fruits that adds num_apples and num_oranges.

R Programming

num_apples <- 5
num_oranges <- 3
# Calculate total_fruits by adding num_apples and num_oranges
# Your code here

Need a hint?

Use the + operator to add the two variables.

3

Write an R Markdown sentence with inline code

Write a character string variable called sentence that contains the text: "I have a total of `r total_fruits` fruits." Use backticks and r to include total_fruits inline as in R Markdown.

R Programming

num_apples <- 5
num_oranges <- 3
total_fruits <- num_apples + num_oranges
# Create sentence with inline R code for total_fruits
# Your code here

Need a hint?

Use double quotes for the string and include `r total_fruits` exactly inside.

4

Print the sentence

Use print(sentence) to display the sentence with inline R code.

R Programming

num_apples <- 5
num_oranges <- 3
total_fruits <- num_apples + num_oranges
sentence <- "I have a total of `r total_fruits` fruits."
# Print the sentence
# Your code here

Need a hint?

Use the print() function to show the sentence.
