fmt_int: Convert integers into same-length strings

In toniprice/jute: Sundry Utility Functions

Convert integers into same-length strings

Description

Converts an integer value or vector of integer values into string(s) without any decimal point, padding them with a leading character to ensure they are all the same length.

Usage

fmt_int(num, tol = 1e-08, pad_char = " ", preserve_names = FALSE)

Arguments

num	An integer vector of values to be converted (these do not need to be of class integer but they do need to be 'integerish', i.e. without any digits after the decimal points).
tol	The numerical tolerance used to check whether a double can be safely converted to an integer.
pad_char	The character to use for (left) padding to ensure same-length output.
preserve_names	TRUE to preserve names from the input vector, FALSE otherwise.

Value

A character vector of formatted integer values, left-padded to the length of the largest value with the specified padding character.

Examples

fmt_int(2) # => "2"
fmt_int(2.0) # => "2"
fmt_int(2.00001, tol = 1.0e-4) # => "2"
fmt_int(c(2, 467, 25)) # => [1] "  2" "467" " 25"
fmt_int(c(2, 467, 25), pad_char=".") # => [1] "..2" "467" ".25"
fmt_int(c(a = 1, b = 20), preserve_names = TRUE)
