# How to obtain the dimension of a given matrix in R Onyejiaku Theophilus Chidalu

### Overview

To understand what a matrix is and how to create a matrix in R, click here.

### Obtaining the dimension of a matrix

To obtain the dimension of a matrix in R, we use the dim() function.

### Syntax

dim(matrix)


### Parameter

The dim() function takes a single parameter, which is the matrix object.

### Return value

The dim() function returns the dimension of a matrix passed to it.

### Example

# creating a matrix
mymatrix <- matrix(c("apple", "banana", "cherry", "orange"), nrow = 2, ncol = 2)

# implementing the dim() function
dim(mymatrix)
Implementing the dim() function

### Explanation

We create 2x2 matrix (a matrix with 2 rows and 2 columns) mymatrix. Using the dim() function, we check for the dimensions of the matrix. As we can see from the output, it is a 2x2 matrix.
