How to Solve the Error – Subscript Out of Bounds in R (Example Code)
On this page, I’ll illustrate how to fix the error subscript out of bounds in the R programming language.
Introducing Exemplifying Data
example_matrix <- matrix(1:100, # Creating & printing example matrix nrow = 10) example_matrix # [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] # [1,] 1 11 21 31 41 51 61 71 81 91 # [2,] 2 12 22 32 42 52 62 72 82 92 # [3,] 3 13 23 33 43 53 63 73 83 93 # [4,] 4 14 24 34 44 54 64 74 84 94 # [5,] 5 15 25 35 45 55 65 75 85 95 # [6,] 6 16 26 36 46 56 66 76 86 96 # [7,] 7 17 27 37 47 57 67 77 87 97 # [8,] 8 18 28 38 48 58 68 78 88 98 # [9,] 9 19 29 39 49 59 69 79 89 99 # [10,] 10 20 30 40 50 60 70 80 90 100 |
example_matrix <- matrix(1:100, # Creating & printing example matrix nrow = 10) example_matrix # [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] # [1,] 1 11 21 31 41 51 61 71 81 91 # [2,] 2 12 22 32 42 52 62 72 82 92 # [3,] 3 13 23 33 43 53 63 73 83 93 # [4,] 4 14 24 34 44 54 64 74 84 94 # [5,] 5 15 25 35 45 55 65 75 85 95 # [6,] 6 16 26 36 46 56 66 76 86 96 # [7,] 7 17 27 37 47 57 67 77 87 97 # [8,] 8 18 28 38 48 58 68 78 88 98 # [9,] 9 19 29 39 49 59 69 79 89 99 # [10,] 10 20 30 40 50 60 70 80 90 100
Example: Fix the Error Message: Subscript Out of Bounds
This works, since the matrix has a fifth column.
example_matrix[ , 5] # Print only one column # [1] 41 42 43 44 45 46 47 48 49 50 |
example_matrix[ , 5] # Print only one column # [1] 41 42 43 44 45 46 47 48 49 50
This does not work, because the matrix does not have a 20th column.
example_matrix[ , 20] # Try to return non-existing column # Error in example_matrix[, 20] : subscript out of bounds |
example_matrix[ , 20] # Try to return non-existing column # Error in example_matrix[, 20] : subscript out of bounds
