# Split Number into Digits in R (2 Examples)

In this article youâ€™ll learn how to convert a number into digits in R.

## Importing the TeachingDemos Package

For the examples of this tutorial, weâ€™ll first have to load the TeachingDemos package:

```install.packages("TeachingDemos")           # Install & load TeachingDemos
library("TeachingDemos")```

## Example 1: Split Single Number into Digits

In this example, Iâ€™ll explain how to divide a single number into digits.

Letâ€™s create a data object containing such a number:

```x1 <- 13579                                 # Create single example number
x1                                          # Print example number
# [1] 13579```

Next, we can apply the digits() function of the TeachingDemos package to split our number into digits:

```x1_split1 <- digits(x1)                     # Split number into digits
x1_split1                                   # Print digits output
# [1] 1 3 5 7 9```

We may also use the n argument of the digits function to add several 0 digits in front of the output:

```x1_split2 <- digits(x1, n = 10)             # Specify number of digits
x1_split2                                   # Print digits output
#  [1] 0 0 0 0 0 1 3 5 7 9```

## Example 2: Split Vector of Numbers into Digits

The following syntax illustrates how to separate a vector of numbers into digits.

Once again, letâ€™s create some example data:

```x2 <- c(1, 222, 56789)                      # Create vector of numbers
x2                                          # Print vector of numbers
# [1]     1   222 56789```

If we apply the digits function to this vector, a list object is returned. Each of the list elements corresponds to one of the vector elements:

```x2_split1 <- digits(x2)                     # Split vector of numbers
x2_split1                                   # Print digits output
# [[1]]
# [1] 1
#
# [[2]]
# [1] 2 2 2
#
# [[3]]
# [1] 5 6 7 8 9```

We can also use the simplify argument to return a matrix instead of a list:

```x2_split2 <- digits(x2, simplify = TRUE)    # Matrix of digits
x2_split2                                   # Print digits output```

Furthermore, we might combine the digits function with the unlist function to convert the output to a vector of digits:

```x2_split3 <- unlist(digits(x2))             # Convert list into vector
x2_split3                                   # Print digits output
# [1] 1 2 2 2 5 6 7 8 9```
