4. Get comfortable working in tight quarters: When working on large datasets or when trying new ways of doing things, it’s always good advice practice “tight quarters” – stay focused and concentrated while working on a project rather than spreadsheets or text editor windows all around you (this can also help improve productivity). This means spending time within one window or file rather than taking breaks between files or windows multiple times throughout the day.
5. Use feedback loops: Always test your code before release so that changes made during development result in improved accuracy and clarity of your code later on (this is often called “trying out” code).
2. What is R.
R is a powerful programming language that is used for data science and machine learning. R has been known to be fast, versatile, and easy to learn.
