I need to add some superscript or symbols into fig.cap. I have tried "expression" function, but didn't work for me. How could I achieve it?

Thanks for any suggestions.

This in my Rmd file for example.

---
title: "Untitled"
author: ""
date: "Wednesday, September 24, 2014"
output: 
    word_document:
        fig_caption: true

---

```{r, echo=1,fig.cap=expression('The unit (% y'^-1*')')}
plot(cars)
```

    The `?plotmath` commands only work inside the graphics device. If you want to put the title as the the `main=` title in your `plot()`, you can do that. But if you want the text/type of the document to have superscripts, then you need to add it as markup, not an expression.

    LaTeX + Mathjax could be your friend here, at least it works in pdf and html output, I don't know if pandoc supports math conversion to Word. – baptiste Sep 24 '14 at 12:30
