Different data structures in R

Question

Hey! I am new to R and I want to know the different data structures in R!!

Can someone please help?

Answer 1

Broadly speaking these are Data Structures available in R:

• 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).
  • A data frame combines features of matrices and lists. In fact we can consider a data frame as a rectangular list.

Answer 2

The different data types in R are as below.

List

Vector

Matrix - 2D representation of data.

Array - A multidimensional matrix or many matrices.

Tibble - table representation of data.

Dataframe - table representation of data.
