pad: Pad a number with leading zeros

In drmjc/mjcbase: General helper functions for dealing with \R objects/data types

Description

Convert a number to a string, and pad out the resulting character with "0" at the start.

Usage

pad(int, strWidth = NULL, atEnd = FALSE)

Arguments

int	a numeric vector, or character vector of numbers
strWidth	the desired width. If NULL, and length(int)>1, then this is determined automatically. If NULL, and length(int)==1, then a single “0” is added.
atEnd	logical: pad at the end (TRUE), or start (FALSE)?

Details

Can supply strWidth to specify the number of characters desired in the final string. If it's not supplied, then a single "0" is prepended. If int is a vector of numbers, strWidth is automatically set so that they all have the same number of characters.

Value

a charcter vector, all with the same nchar.
