The course is part of this learning path
This module looks at more complex data structures, building on what was covered in the intermediate data structures module.
The objectives of this module are to provide you with an understanding of:
- How to construct a factor in R
- How to construct a data frame in R
- How to modify a data frame
- How to subset a data frame
- Data frames automatically factorising data in R
Aimed at all who wish to learn the R programming language.
No prior knowledge of R is assumed.
Delegates should already be familiar with basic programming concepts such as variables, scope, and functions.
Experience of another scripting language such as Python or Perl would be an advantage.
Understanding mathematical concepts will be beneficial.

- Once we have the component hierarchy outlined, we can build a version that takes our data model and renders it without interactivity. Decoupling the view and interactivity is good, as static versions are lots of typing and little thinking and vice versa. The established best practice is to build components that reuse other components and pass data using props. We won't be using state here, because that is used for interactivity. A top-down approach to building our components is as acceptable as a bottom-up approach. Although this bottom-up approach is more common in TDD environments. Doing all this helps to establish a library of reusable components to render each data model from. Each component only has a return JSX expression and any minimal logic to help create it. To effectively do this you need to understand what props are, and the mechanisms that are used to pass props down the component tree. It would also be handy to know about default props, and how you can type safe invalidate props and components using prop types. If you're not familiar with these ideas, I suggest leveling up your skills on props using our lining materials before continuing with the thinking in react track.
