R's computational core, covering fundamental data types, vectorized operations, and advanced data structures including matrices, arrays, lists, factors, and data frames. It emphasizes efficient numerical computation, logical and character vector operations, and structured data manipulation, along with R's object-oriented systems (S3, S4, and Reference Classes) for building modular, scalable programs. The focus is on computation-oriented programming principles essential for statistical computing and data-centric applications.
