\title{Format numbers using SI unit prefixes}
\usage{
numbers2prefix(number, rounding = FALSE, digits = ifelse(rounding, NA, 6))
}
\arguments{
\item{number}{number, numeric vector}

\item{rounding}{rounds number to nearest integer (default FALSE), boolean}

\item{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)
}
\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).
