title: Making bubble chart with R
body: <p>I have a table with the abundance of species in multiple samples. I want to make a bubble chart where in the y-axis I will have the different species, in the x-axis the different samples in which I found those species, while the radius of the bubbles will suggest the relative size of the species.</p>
  
  <p>My table is something like this:</p>
  
  <pre><code>Samples Sample1 Sample2 Sample3 Sample4 Sample5
  Species1    12  25  25  25  25
  Species2    12  23  23  23  23
  Species3    12  21  21  21  21
  Species4    12  19  19  19  19
  Species5    12  17  17  17  17
  Species6    1   15  15  15  15
  Species7    5   13  13  13  13
  </code></pre>
  
  <p>I want to end up with something like <a href="http://www.frontiersin.org/files/Articles/254835/fmicb-08-00666-HTML/image_m/fmicb-08-00666-g002.jpg" rel="nofollow noreferrer">this</a>:</p>
