What is a matrix in R?
- A one-dimensional array of elements of the same data type
- A two-dimensional data structure with rows and columns
- A collection of elements of different data types
- A function that performs operations on a set of data
In R, a matrix is a two-dimensional data structure with rows and columns. It is a collection of elements of the same data type organized in a rectangular format. Matrices are particularly useful for storing and manipulating numeric or character data that can be arranged in a tabular form, such as datasets or matrices in mathematics.
