After mastering the basics of R, you're now ready to expand your R toolkit and learn some essential data analysis skills. In this course, we'll take a look at the list data structure, learn all there is to know about functions, and perform one-line coding wizardry with "apply" functions.

Lists are special data structures in R, but they're present in many other programming languages, too. R list is just an unordered collection of objects; these objects can range from anything like single values to vectors, data frames, and even other lists! Lists are especially popular in R data analysis, so it's important that you learn them well.

Functions allow us to write abstract, reusable code. You've already worked with many built-in functions in R (and possibly other languages as well). Suffice to say that writing and using functions is a fundamental skill for data analysis, so we'll help you unpack everything about R functions.

A special family of functions allows you to apply a given function to each member of R list, data frame, or vector. These functions include lapply(), sapply(), and tapply(). We'll teach you how to use these "apply" functions to perform powerful data analysis in R with just a single line of code!

Looking for hands-on practice with the material? There's plenty to go around! We've carefully designed 105 exercises to present you with real-world business problems.

  • Just a web browser and an Internet connection.
  • We assume you've completed Introduction to R; we'll build on that knowledge here.

Learn How To:

  • Use R list to perform more complex data analysis.
  • Create your own functions for analyzing data.
  • Use conditional "if" statements in your code, especially within functions.
  • Manipulate data more efficiently with the use of lapply(), sapply() and tapply().

Who Should Take This Course?

  • Students who already passed Introduction to R.
  • Data and business analysts who want to go beyond data frames and perform more complex data analysis.
  • Those who are interested in data science and data analysis and are familiar with the basics of R.
  • Anyone who wants to go deeper into the R programming world.
