Numeric type in R Programming - Mini Project: Build & Apply

Working with Numeric Types in R

📖 Scenario: You are helping a small business owner track daily sales amounts. The sales amounts are numbers that include decimals.

🎯 Goal: You will create a numeric vector of sales amounts, set a threshold value, filter sales above the threshold, and print the filtered sales.

📋 What You'll Learn

Create a numeric vector with exact sales amounts

Create a numeric threshold variable

Use a logical condition to filter sales above the threshold

Print the filtered sales vector

💡 Why This Matters

🌍 Real World

Tracking and analyzing sales amounts helps businesses understand their performance and make decisions.

💼 Career

Data analysts and business managers often work with numeric data to filter and summarize important information.

1

Create the sales data vector

Create a numeric vector called sales with these exact values: 23.5, 45.0, 12.75, 67.25, and 34.0.

R Programming

# Create the numeric vector sales with the given values
# Your code here

Need a hint?

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

2

Set the sales threshold

Create a numeric variable called threshold and set it to 30.

R Programming

sales <- c(23.5, 45.0, 12.75, 67.25, 34.0)
# Create the numeric variable threshold and set it to 30
# Your code here

Need a hint?

Assign the number 30 to the variable threshold using the assignment operator <-.

3

Filter sales above the threshold

Create a new vector called high_sales that contains only the values from sales that are greater than threshold.

R Programming

sales <- c(23.5, 45.0, 12.75, 67.25, 34.0)
threshold <- 30
# Create high_sales with sales values greater than threshold
# Your code here

Need a hint?

Use logical indexing with sales > threshold inside square brackets to filter the vector.

4

Print the filtered sales

Print the high_sales vector to display the sales amounts greater than the threshold.

R Programming

sales  threshold]
# Print the high_sales vector
# Your code here

Need a hint?

Use the print() function to display the vector.
