<p><strong>This is <code>R</code> code:</strong></p>
<pre><code>lm(rnorm(10) ~ I(rnorm(10)))
</code></pre>
<p>It has been formatted according to the new method (here on CV) of preceding and following it with a left-justified row of three backticks ```.  The user can copy everything directly because there are no extra formatting marks within the block itself -- not even indentation.</p>
<p><strong>This is its output:</strong></p>
<blockquote>
<pre><code>Call:
lm(formula = y ~ x)

Coefficients:
(Intercept)            x  
     0.5912      -0.7138
</code></pre>
</blockquote>
<p>The latter was formatted first as a code block then that itself was quoted, producing the vertical line to the left that visually distinguishes the output from the code.  These are fast, easy steps: select the text and hit the appropriate icon above the textbox.</p>
