R data structures

There are numerous types of data structures across programming languages, each with strengths and weaknesses specific to particular tasks. Since R is a programming language used widely for statistical data analysis, the data structures it utilizes are designed to make it easy to manipulate data for this type of work. The R data structures used most frequently in machine learning are vectors, factors, lists, arrays, and data frames. Each of these data types is specialized for a specific data management task, which makes it important to understand how they will interact in your R project.
