title: How to change plot size in R?
body: <p>I would like to create two plots side-by-side, but the problem I am running into is that R seemingly can not enlarge the &quot;plotting space&quot;, which results in shrinkage of both graphs on the x-axis like so:

  <p>You can also see that the line names also get cropped due to not enough space being present. Sow the question is: how do I make the plots wider and the labels fully visible? It would be great to avoid any libraries like <code>ggplot</code>, but if there is no other way, this will be fine as well.</p>
  <p>Here is how the plots above are constructed:</p>
  <pre><code>layout(matrix(c(1,2), 1, 2, byrow = TRUE))  
  plot(plot1)
  plot(plot2) # axis(4, at = coef1[nrow(coef1), ], labels = colnames(coef1), cex = 0.8, adj = 0, las=2) 
  </code></pre>
