# How to Create a List of Multiple Matrices in R (Example Code)

In this article, I’ll show how to combine multiple matrices in a list object in the R programming language.

## Introduction of Exemplifying Data

```my_matrix_a <- matrix(LETTERS[10:21], # First list nrow = 3) my_matrix_a # [,1] [,2] [,3] [,4] # [1,] "J" "M" "P" "S" # [2,] "K" "N" "Q" "T" # [3,] "L" "O" "R" "U"```
```my_matrix_b <- matrix(101:120, # Second list nrow = 5) my_matrix_b # [,1] [,2] [,3] [,4] # [1,] 101 106 111 116 # [2,] 102 107 112 117 # [3,] 103 108 113 118 # [4,] 104 109 114 119 # [5,] 105 110 115 120```

## Example: Insert Multiple Matrices into New List

```list_of_matrices <- list(my_matrix_a, # Store matrices in list my_matrix_b) list_of_matrices # Final output # [[1]] # [,1] [,2] [,3] [,4] # [1,] "J" "M" "P" "S" # [2,] "K" "N" "Q" "T" # [3,] "L" "O" "R" "U" # # [[2]] # [,1] [,2] [,3] [,4] # [1,] 101 106 111 116 # [2,] 102 107 112 117 # [3,] 103 108 113 118 # [4,] 104 109 114 119 # [5,] 105 110 115 120```
