Error to present two plots in one panel with word_document2

[sammo3182]

I tried to present two plots in one panel using the bookdown::word_document2. The specification are as following:

---
output: bookdown::word_document2
---

```{r fig.cap='A figure example with the specified aspect ratio, width, and alignment.', fig.show="hold"}
plot(pressure, pch = 19, type = 'b')
plot(pressure$temperature)
```

The codes produce the following error of label once I specified fig.show="hold". The same codes work fine in pdf_document2 or without the arugment fig.show="hold".

Error in parse_fig_labels(x, global) : 
  There are multiple labels on one line: (#fig:unnamed-chunk-1), (#fig:unnamed-chunk-1)
Calls: <Anonymous> ... <Anonymous> -> process_markdown -> parse_fig_labels
Execution halted

I'm using the developed version of bookdown (0.2.4).

fig.show='hold' does not really work for Word output. I just added a warning in the development version of knitr.

Thank you for the reply. It could be more convenient, though if the compiling of bookdown::word_document2 can just ignore the fig.show option as the word_document does even if the function cannot be correctly transferred to MS Word. In that case, users do not need to change the codes in the content but the header to successfully compile the codes and use the cross-reference function of markdown.

That is exactly what I did in the development version of knitr.

Great! Thank you for keeping improving these valuable packages!!
Just tried the developing version of knitr. The multiple labels on one line still appears, though, when the fig.show is involved.

The error has been fixed (see #538).
