strsplit in R Programming - Mini Project: Build & Apply

Splitting Strings with strsplit in R

📖 Scenario: You work in a small bakery that keeps a list of customer orders as single strings. Each order lists items separated by commas. You want to split these strings into individual items to better understand what customers want.

🎯 Goal: Learn how to use the strsplit function in R to split strings into parts based on a separator.

📋 What You'll Learn

Create a character vector with exact order strings

Create a separator variable with the exact comma character

Use strsplit with the vector and separator

Print the resulting list of split items

💡 Why This Matters

🌍 Real World

Splitting strings is useful when processing text data like customer orders, CSV files, or logs where data is combined in one string.

💼 Career

Many data jobs require cleaning and splitting text data to analyze or transform it for reports, databases, or machine learning.

1

Create the orders vector

Create a character vector called orders with these exact strings: "bread,butter,jam", "cake,coffee", and "tea,cookie".

R Programming

# Create the character vector orders with the exact strings
# Your code here

Need a hint?

Use the c() function to create a vector of strings.

2

Create the separator variable

Create a variable called separator and set it to the exact string "," (a comma).

R Programming

orders <- c("bread,butter,jam", "cake,coffee", "tea,cookie")
# Create the separator variable with the comma string
# Your code here

Need a hint?

Remember to put the comma inside quotes to make it a string.

3

Split the orders using strsplit

Use strsplit with orders and separator to create a new variable called split_orders.

R Programming

orders <- c("bread,butter,jam", "cake,coffee", "tea,cookie")
separator <- ","
# Use strsplit to split orders by separator and save to split_orders
# Your code here

Need a hint?

Use strsplit(orders, separator) and assign it to split_orders.

4

Print the split orders

Print the variable split_orders to see the list of split items.

R Programming

orders <- c("bread,butter,jam", "cake,coffee", "tea,cookie")
separator <- ","
split_orders <- strsplit(orders, separator)
# Print split_orders
# Your code here

Need a hint?

Use print(split_orders) to display the result.
