## 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
