This is a DataCamp course: In the real world, data sets typically come split across many tables while most data analysis functions in R are designed to work with single tables of data. In this course, you'll learn how to effectively combine data sets into single tables using data.table. You'll learn how to add columns from one table to another table,
how to filter a table based on observations in another table, and how to identify records across multiple tables matching complex criteria. Along the way, you'll learn how to troubleshoot failed join operations and best practices for working with complex data sets. After completing this course you'll be well on your way to be a data.table master!

Very helpful course, but the instructions to the excercises are often misleading or unclear. In the end it doesn't matter, you will know how to join tables very well.

Was nice, but would let the user make more formulas completely from scratch instead of just filling in arguments
