Character (string) type in R Programming - Mini Project: Build & Apply

Working with Character (string) Type in R

📖 Scenario: You are creating a simple program to store and display names of fruits. This will help you understand how to work with character (string) data in R.

🎯 Goal: Build a small R script that stores fruit names as strings, counts how many fruits are in the list, extracts a specific fruit, and prints the results.

📋 What You'll Learn

Create a character vector with exact fruit names

Create a variable to store the number of fruits

Extract a specific fruit from the vector

Print the number of fruits and the extracted fruit

💡 Why This Matters

🌍 Real World

Working with character data is common when handling names, labels, or any text information in data analysis or software.

💼 Career

Knowing how to store and manipulate strings is essential for data cleaning, reporting, and user interface programming.

1

Create a character vector of fruits

Create a character vector called fruits with these exact values: "apple", "banana", "cherry", "date", "elderberry".

R Programming

# Create a character vector called fruits with the given fruit names
# Your code here

Need a hint?

Use the c() function to combine strings into a vector.

2

Count the number of fruits

Create a variable called num_fruits that stores the number of elements in the fruits vector using the length() function.

R Programming

fruits <- c("apple", "banana", "cherry", "date", "elderberry")
# Create num_fruits to store the count of fruits
# Your code here

Need a hint?

Use length(fruits) to find how many fruits are in the vector.

3

Extract a specific fruit

Create a variable called second_fruit that stores the second fruit in the fruits vector using indexing.

R Programming

fruits <- c("apple", "banana", "cherry", "date", "elderberry")
num_fruits <- length(fruits)
# Extract the second fruit and store it in second_fruit
# Your code here

Need a hint?

Use square brackets [] to get the second item from the vector.

4

Print the results

Print the number of fruits using print(num_fruits) and print the second fruit using print(second_fruit).

R Programming

fruits <- c("apple", "banana", "cherry", "date", "elderberry")
num_fruits <- length(fruits)
second_fruit <- fruits[2]
# Print num_fruits and second_fruit
# Your code here

Need a hint?

Use print() to show the values on the screen.
