Introduction to R, Part 3 of 3: Working with Data

Programmers, data analysts, data scientists, and anyone who works with data has probably spent many hours staring at data organized into rows and columns. Those data structures are referred to as spreadsheets or tables and they form the basis for much of the data manipulation done today. Finish the first leg in your R journey with a look at two special objects in R used to work with tabular, or tabled data: the Data Frame and Data Table. Explore their internal structure, how to create them, and how they can be manipulated, queried, filtered, joined, grouped, or sorted just as if they were database table objects. Lastly, take a look at some helpful functions in R which can be used to streamline your code.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.
