title: r plots with unequal length of x and y axes
body: <p>I want to use r to plot data points in an area whose x and y axes are of unequal length.</p>
  
  <p>Specifically, the coordinates range from -136 to 136 on the X Axes, and from 0 to 420 on the y axes.</p>
  
  <p>my naive approach to create a plot that would fit the data with </p>
  
  <pre><code>plot(x=-136:136, y=0:420, type= "n", main="distribution", xlab='xdescr', ylab='ydescr')
  </code></pre>
  
  <p>fails with </p>
  
  <pre><code>Error in xy.coords(x, y, xlabel, ylabel, log) : 
  'x' and 'y' lengths differ
  </code></pre>
  
  <p>(How) is it possible to create a plot that fits this data? Is it inevitable to create a plot with equal axes length?</p>
  
  <p><strong>edit:</strong> the plotted area itself must not be square because the values represent the same (distance) along both axes</p>
  
  <p><strong>edit:</strong> I tried the solution suggested here <a href="https://stackoverflow.com/questions/19323292/how-to-get-a-non-square-plot-in-r">How to get a non-square plot in R?</a>. That doesn't produce a plot like I want - the result is stretched in the wrong direction (landscape-y rather than portrait-y)</p>
