ggplot annotation - superscript with paste
<p>I have been through all the top posts on ggplot superscript in annotation (expression, bquote, etc), and none have done the trick. Appreciate your help.</p>

<pre><code>df &lt;- data.frame(x =  rnorm(10), y = rnorm(10))
var1&lt;-"SR"
var2&lt;-10
mylabel&lt;-paste(var1," at ", var2, "m^2 scale")

ggplot(df, aes(x = x, y = y)) + geom_point() +
  annotate("text", x = mean(df$x), y = mean(df$y),label = "test", parse=T)
</code></pre>
