title: Adjust the output width of R Markdown HTML output
body: <p>I am producing an HTML output but I am having issues with the output width of R code output.</p>
  
  <p>I'm able to adjust the figure width with no difficulty but when I try to write a data table or the factor loadings, R is outputting at a fixed width which is only about a third of my screen width.  This results in the columns of the table being split up rather than all of the columns displayed in a single table.</p>
  
  <p>Here is a reproducible example:</p>
  
  <pre><code>---
  output: html_document
  ---
  
  # Title
  
  ```{r echo = FALSE, fig.width=16, fig.height=6}
  x = matrix(rnorm(100),ncol=10)
  x
  plot(x)
  ```
  </code></pre>
