问题
When kniting a Rmarkdown file to MS Word, is there a way to have equations labled with a number that is flushed to the right?
For example:
When typing this in Rmarkdown:
$$a + b = c$$
I need it to end up in Word as:
a + b = c (1)
I saw the code below somewhere else, but it does not seem to work when kniting to Word...
\begin{equation}
\label{eq-abc}
a + b = c
\end{equation}
Thanks!

@Sholom's comment regarding pandoc-crossref inspired me to have a read, I was not previously aware of it and it is not available as an extension to rmarkdown currently.
It is entirely possible to achieve basic equation numbering with this "filter".
Markdown

output:
word_document:
pandoc_args: ["-Fpandoc-crossref"]
---
$$a^2 + b^2 = c^2$$ {#eq:eqn1}
$$\log xy = \log x + \log y$$ {#eq:eqn2}
$$\frac{df}{dt} = \lim_{h\to0}\frac{f(t+h)-f(t)}{h}$$ {#eq:eqn3}
Output
pandoc-crossref
The binary releases of the code are located here. From a windows machine, I dropped the pandoc-crossref.exe into my Pandoc install folder alongside pandoc.exe and that was sufficient to allow my markdown to render.
N.B. I did this with a standalone install of Pandoc, if you are using the version bundled with RStudio you may need to install differently.
