Format numbers using SI unit prefixes

Description

Using SI unit prefixes is a more compact way to write very large or very small numbers which can sometimes be useful. This function takes a number (or a vector of numbers) and returns the equivalent value expressed using the nearest prefix. My thanks to https://stackoverflow.com/users/843265/tomelgin for posting the code that this function was based on (see first link below).

Usage

numbers2prefix(number, rounding = FALSE, digits = ifelse(rounding, NA, 6))

Arguments

number	number, numeric vector
rounding	rounds number to nearest integer (default FALSE), boolean
digits	if rounding=FALSE, lets you specify significant figures (default 6), numeric

Value

number followed by SI prefix (as character string, separated by narrow no-break space)
