Intermediate R: Practice

If conditionals are your thing, these exercises will be a walk in the park. Else, let the feedback guide you and add these vital elements of R to your toolkit!

Looping through data structures is something you'll often do. While and for loops help you do this. Get more practice on them by analyzing the log data from a chemical plant.

Functions make R powerful: you can isolate chunks of code, wrap them in a function and use them whenever you want. In this set of exercises, you'll practice more on using functions and writing your own functions.

lapply, sapply and vapply are all members of R's apply family: they provide a fast and intuitive alternative to the while and for loops you've learned about before. Become an apply pro with some more practice!

To finish off these supplementary exercises, you can exercise some more with often-used functions in R, regular expressions and manipulating dates and times.
