title: How can I increase the margins for the R function, pheatmap?
body: <p>I am plotting a heatmap using pheatmap (<a href="https://cran.r-project.org/web/packages/pheatmap/pheatmap.pdf" rel="nofollow noreferrer">Documentation</a>). I am plotting a matrix in a fairly straightforward way:</p>
  
  <pre><code>pheatmap(mat, annotation_col=df, labels_col=rld$Infection_Line, fontsize_row=5, fontsize_col=7) 
  </code></pre>
  
  <p>The bottom of my plot is getting cut off so that I can't see the column names at the bottom.  It looks like this: <a href="https://i.stack.imgur.com/LrBS7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/LrBS7.png" alt="enter image description here"></a>
  I have tried to increase the margins using par() and oma(), as well as cexRow=... </p>
  
  <p>I need to make it so that I can see these long column names without reducing my plot size.  I just want to stretch the margin at the bottom down.  Does anyone know how to do this?  </p>
  
  <p>Thanks in advance.</p>
