Return the digits that make up an integer
Description
Takes an integer or vector of integers and returns a vector, list, or matrix of the individual digits (decimal) that make up that number.
Usage
digits(x, n = NULL, simplify = FALSE)
Arguments
x |
An integer or vector of integers (if not integer, the fractional part will be ignored) |
n |
The number of digits to be returned, this can be used to place 0's
in front of smaller numbers. If this is less than the number of
digits then the last |
simplify |
Should |
Details
This function transforms an integer (or real ignoring the fractional part) into the decimal digits that make of the decimal representation of the number using modular mathematics rather than converting to character, splitting the string, and converting back to numeric.
Value
If x
is of length 1 then a vector of the digits is returned.
If x
is a vector and simplify
is FALSE
then a list
of vectors is returned, one element for each element of x
.
If x
is a vector and simplify
is TRUE
then a
matrix with 1 column for each element of x
.
