Vector creation with c() in R Programming - Mini Project: Build & Apply

Vector creation with c()

📖 Scenario: You are helping a small shop owner organize their daily sales data. They want to keep track of the number of items sold each day in a simple list.

🎯 Goal: Create a vector using the c() function in R to store the number of items sold each day for a week.

📋 What You'll Learn

Create a vector called sales with the exact values: 5, 8, 6, 7, 9, 4, 10

Create a variable called days and set it to 7

Use a for loop with variable i to iterate over the sales vector

Calculate the total sales in a variable called total_sales

Print the total sales using print(total_sales)

💡 Why This Matters

🌍 Real World

Tracking daily sales helps shop owners understand their business performance and plan better.

💼 Career

Data analysts and business managers often work with vectors and loops to process and summarize data.

1

Create the sales vector

Create a vector called sales using the c() function with these exact values: 5, 8, 6, 7, 9, 4, 10

R Programming

# Create the sales vector with the exact values
# Your code here

Need a hint?

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

2

Set the number of days

Create a variable called days and set it to 7

R Programming

sales <- c(5, 8, 6, 7, 9, 4, 10)
# Create the variable days and set it to 7
# Your code here

Need a hint?

Just assign the number 7 to the variable days.

3

Calculate total sales with a loop

Create a variable called total_sales and set it to 0. Then use a for loop with variable i to iterate over the sales vector and add each value to total_sales

R Programming

sales <- c(5, 8, 6, 7, 9, 4, 10)
days <- 7
# Initialize total_sales to 0
# Use a for loop with i to add each sales value to total_sales
# Your code here

Need a hint?

Start with total_sales <- 0. Then use for (i in sales) to loop through each number and add it to total_sales.

4

Print the total sales

Write print(total_sales) to display the total number of items sold in the week

R Programming

sales <- c(5, 8, 6, 7, 9, 4, 10)
days <- 7
total_sales <- 0
for (i in sales) {
  total_sales <- total_sales + i
}
# Print the total_sales
# Your code here

Need a hint?

Use print(total_sales) to show the result.
