Factor creation in R Programming - Mini Project: Build & Apply

Factor creation

📖 Scenario: You work in a small company that collects survey data about customer satisfaction. The survey answers are stored as text, but you want to organize them better for analysis.

🎯 Goal: You will create a factor variable in R from a character vector of survey answers. This will help group and analyze the answers easily.

📋 What You'll Learn

Create a character vector with exact survey answers

Create a factor variable from the character vector

Specify the levels of the factor in a given order

Print the factor variable to see the result

💡 Why This Matters

🌍 Real World

Survey data often comes as text answers. Converting them to factors helps organize and analyze the data efficiently.

💼 Career

Data analysts and statisticians use factors to handle categorical data in R for reports and visualizations.

1

Create the survey answers vector

Create a character vector called answers with these exact values: "Yes", "No", "Maybe", "Yes", "No".

R Programming

# Create the character vector answers with the given values
# Your code here

Need a hint?

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

2

Create the factor variable

Create a factor variable called answers_factor from the answers vector using the factor() function.

R Programming

answers <- c("Yes", "No", "Maybe", "Yes", "No")
# Create the factor variable answers_factor from answers
# Your code here

Need a hint?

Use factor(answers) to convert the character vector to a factor.

3

Specify the factor levels order

Create the factor variable answers_factor again from answers, but this time specify the levels in this exact order: "No", "Maybe", "Yes".

R Programming

answers <- c("Yes", "No", "Maybe", "Yes", "No")
# Create answers_factor with levels ordered as "No", "Maybe", "Yes"
# Your code here

Need a hint?

Use the levels argument inside factor() to set the order.

4

Print the factor variable

Print the answers_factor variable to display its values and levels.

R Programming

answers <- c("Yes", "No", "Maybe", "Yes", "No")
answers_factor <- factor(answers, levels = c("No", "Maybe", "Yes"))
# Print the answers_factor variable
# Your code here

Need a hint?

Use print(answers_factor) to show the factor values and their levels.
