Data structures in R
Here we will be looking at the most useful data structures which exist in R and use using them on some fictional examples to get a better grasp on their syntax and constructs. The main data structures which we will be covering here include:
- Vectors
- Arrays and matrices
- Lists
- Data frames
These data structures are used widely inside R as well as by various R packages and functions, including machine learning functions and algorithms which we will be using in the subsequent chapters. So it is essential to know how to use these data structures to work with data efficiently.
Vectors
Just like we mentioned briefly in the previous sections, vectors are the most basic data type inside R. We use vectors to represent anything, be it input or ...
