| Data Structure | Description |
| Vector | A vector is a sequence of data elements of the same basic type. Members in a vector are called components. |
| List | Lists are the R objects which contain elements of different types like − numbers, strings, vectors or another list inside it. |
| Matrix | A matrix is a two-dimensional data structure. Matrices are used to bind vectors from the same length. All the elements of a matrix must be of the same type (numeric, logical, character, complex). |
| Dataframe | A data frame is more generic than a matrix, i.e different columns can have different data types (numeric, character, logical, etc). It combines features of matrices and lists like a rectangular list. |
