Units on the y axis are drawn at <code>ratio</code> times the size of units on the x axis. Ignored if <code>uin</code> is specified and of length 2. </p> </td></tr> <tr valign="top"><td><code>tol</code></td> <td> <p>proportion of white space at the margins of plot </p> </td></tr> <tr valign="top"><td><code>uin</code></td> <td> <p>desired values for the units-per-inch parameter. If of length 1, the desired units per inch on the x axis. </p> </td></tr> <tr valign="top"><td><code>...</code></td> <td> <p>further arguments for <code>plot</code> and graphical parameters. Note that <code>par(xaxs="i", yaxs="i")</code> is enforced, and <code>xlim</code> and <code>ylim</code> will be adjusted accordingly. </p> </td></tr></table> <h3>Details</h3> <p>Limits for the x and y axes are chosen so that they include the data. One of the sets of limits is then stretched from the midpoint to make the units in the ratio given by <code>ratio</code>. Finally both are stretched by <code>1 + tol</code> to move points away from the axes, and the points plotted. </p> <h3>Value</h3> <p>invisibly, the values of <code>uin</code> used for the plot. </p> <h3>Side Effects</h3> <p>performs the plot. </p> <h3>Note</h3> <p>Arguments <code>ratio</code> and <code>uin</code> were suggested by Bill Dunlap. </p> <h3>References</h3> <p>Venables, W.
