pad: Pad Strings

In qdapTools: Tools for the 'qdap' Package

Pad Strings

Description

A convenience wrapper for sprintf that pads the front end of strings with spaces or 0s. Useful for creating multiple uniform directories that will maintain correct order.

Usage

pad(x, padding = max(nchar(as.character(x))), sort = TRUE, type = "detect")

Arguments

x	A character, factor, numeric vector.
padding	Number of characters to pad. Default makes all elements of a string the number of characters of the element with the maximum characters.
sort	logical. If TRUE the outcome is sorted.
type	A character string of "detect", "numeric", "character", "d" or "s". If numeric zeros are padded. If character spaces are padded. The detect attempts to determine if x is numeric (d) or not (s).

Value

Returns a character vector every element padded with 0/spaces.

Note

pad is a wrapper for the sprintf function. pad may behave differently on various platforms in accordance with the documentation for sprintf: "actual implementation will follow the C99 standard and fine details (especially the behaviour under user error) may depend on the platform." See sprintf for more information.
