<p>Hmm, scratch that.</p>

<p>Adding <code>&lt;pre&gt;</code> tags just makes this worse as unless you encode html entities like <code>&lt;</code> which is much more of a pain for R code than adding a comment and an extra <code>$</code>. I'll leave this open for a wee while to see if anyone has anything else to suggest/contribute, but otherwise I should probably close or delete this as appropriate.</p>
