## 1. What is R Matrix?

Matix is also called Matrices which is an R data structure that is used to store data in two-dimensional rows and columns. Below are some key points to know and remember about Matrix.

- Matrices or Matrix is a data structure.
- The matrix is two-dimensional.
- It stores data in rows and columns.
- All elements in Matrix should be of the same type (numeric, logical, character, etc.).
- Matrix is a collection of two or more R Vectors.
- R Data Frame is another data structure with two dimensional to store elements of different data types.

## 2. Create Matrix

By using the matrix() function you can create a matrix object in R Programming Language.

```
# Create R matrix
data <- c(10,11,12,13,14,15,16,17,18)
mtx <- matrix(data,nrow=3,ncol=3,byrow=TRUE)
mtx
```

Yields below output.

```
[,1] [,2] [,3]
[1,] 10 11 12
[2,] 13 14 15
[3,] 16 17 18
```

## 3. Access Values of Matrix

## 4. Modify Matrix Values

## Conclusion

In this article, you have learned what is a matrix in R Programming? how to create it? and access its elements. Matrix is a data structure that is used to store values in two-dimensional rows and columns and all elements should be of the same basic type.
