title: plot: Decimal point accuracy on the axis
body: <p>I have two columns of data, <code>X</code> and <code>Y</code> with each entry having 4 places of data after the decimal in both the vectors. </p>
  
  <p>When I make the simple plot with <code>plot(x,y)</code> the axes have the data shown up to 2 decimal point accuracy. How do I change this to a 4 decimal point accuracy, on both axes?</p>
  
  <p>I've added the example data below (<code>inputData</code>), that I have plotted using <code>plot(inputData)</code>.</p>
  
  <pre><code>inputData=structure(list(X = c(33.73521973, 33.622022, 33.63591706, 33.58184488, 
  33.73027696, 33.76169838), Y = c(-112.2559051, -112.2396135, 
  -112.2345327, -112.2441752, -112.2463008, -112.3298128)), .Names = c("X", 
  "Y"), row.names = c(NA, 6L), class = "data.frame")
  </code></pre>
  
  <p>I would like a reproducible example on this above dataset, as well as part of the suggested answer.</p>
  
  <pre><code>&gt; inputData
           X         Y
  1 33.73522 -112.2559
  2 33.62202 -112.2396
  3 33.63592 -112.2345
  4 33.58184 -112.2442
  5 33.73028 -112.2463
  6 33.76170 -112.3298
  </code></pre>
