Building a Command-Line Quiz Application in R

A tutorial demonstrates how to build a command-line quiz application using the R programming language. The project is presented as a practical exercise for data scientists to strengthen fundamental programming skills like control flow, input handling, and modular functions. The guide walks through the process of handling user input with `readline()`, normalizing text, creating a question bank using a list, and looping through questions to keep score. Ultimately, the piece argues that such small, foundational projects are valuable for building skills applicable to more complex data science workflows.
