带knitr的Rstudio中带有标题的表和图编号

Question

In previous iterations of knitr and Rstudio, figure captions with automatic numbering were not supported . But in the newer Rmarkdown it seems they are . Robert Flight had a nice solution which I used before, but I'm wondering if there's a tidier way to do it in the new Rmarkdown. Is there?

Here's as far as I could get with my attempt. Captions are below not above the figures and no numbers are automatically generated.

---
title: "Test for caption"
output: 
  word_document:
    fig_caption: true
---


```{r, fig.cap='oh caption my caption', echo=FALSE} 
require(ggplot2)
ggplot(iris, aes(Petal.Width, Petal.Length, color=Species)) + geom_point()
```

看来您使用的是rmarkdown的旧版本，请尝试将其升级 （> = v0.2.65）。
