The data. frame() function builds data frames, which are tightly coupled collections of variables that have many of the properties of matrices and lists and are utilised as the basic data structure for much of R's modelling applications.

A three-dimensional (r c h) object (think of a collection of stacked r c matrices) is an array. An array's elements must all be of the same data type (character, numeric, or logical). A dataframe is a (r c h) two-dimensional object (like a matrix).

In R programming, use the data.matrix() function to convert a Data Frame into a Numeric Matrix. data. The matrix() function in R creates a matrix by converting all of the values in a Data Frame to numeric mode and then binding them together as a matrix.
