# AxisInPercent: Build Better Looking Axis Labels for Percentages In openintro: Data Sets and Supplemental Functions from 'OpenIntro' Textbooks and Labs

## Description

Convert and simplify axis labels that are in percentages.

## Usage

 `1` ```AxisInPercent(side, at, include.symbol = TRUE, simplify = TRUE, ...) ```

## Arguments

 `side` An integer specifying which side of the plot the axis is to be drawn on. The axis is place as follows: 1 = below, 2 = left, 3 = above and 4 = right. `at` The points at which tick-marks are to be drawn. `include.symbol` Whether to include a dollar or percent symbol, where the symbol chosen depends on the function. `simplify` For dollars, simplify the amount to use abbreviations of `"k"`, `"m"`, `"b"`, or `"t"` when numbers tend to be in the thousands, millions, billions, or trillions, respectively. `...` Arguments passed to `axis`

## Value

The numeric locations on the axis scale at which tick marks were drawn when the plot was first drawn.
