Assignment

This assignment will help you apply the skills you’ve learned in the workshop, including data import, basic data manipulation, control structures (if-else statements, for loops, while loops), and data visualization.

1. if-else statement

• Write a function is_even_or_odd that takes an integer as input and returns “Even” if the number is even and “Odd” if the number is odd.
• Test your function with the numbers 4 and 7.

2. for or while loop

• Use a for loop or while loop to calculate the sum of the squares of the numbers from 1 to 10.

• Print the result.

3. Brunei GDP Data Analysis

• Import the Brunei GDP dataset from the provided CSV file in “data” folder.
• Display the first few rows of the dataset to understand its structure. [Use head()]
• Filter the dataset to include only the years from 2000 onwards. [Use subset(). Use help() to understand the function]
• Create a line plot showing GDP over the years. [Include argument type = "l" for line plot]
• Create a bar plot showing GDP for each year.
• Export the filtered dataset to a new CSV file.

Solutions can be found in the Github repo named solution.R.
