R plot: how to write superscript expression with greek letters?
<p>I am try to write "2 <sup>-ΔΔC<sub>T</sub></sup>" in a Y axes in a graph. Please, note the letter "T" is subscripted in the expression "-ΔΔC<sub>T</sub>".
This is the closest that I could do:</p>

<pre><code>   plot + ylab(expression(paste("2"^{-ddC[T]})))
</code></pre>

<p>Do you have any better suggestion?</p>

<p>Thanks</p>
