html Rmarkdown 中的上图标题 [英] Caption above figure in html Rmarkdown

问题描述

在 RMarkdown 中编织到 HTML 时，是否可以将标题移动到我的图形上方?似乎在 PDF 中是可能的，即

Is it possible to move the caption above my figure when knitting to HTML in RMarkdown? It seems that it is possible in PDF, ie when knitting to PDF, but I can't figure out how to replicate this for HTML. I am using bookdown to number figures.

When I run something like this:

```{r fig.cap= "caption"}
df <- data.frame(letter = letters[1:5], value = 1)

ggplot(df, aes(as(factor(1), value, fill = letters))) +
  geom_bar(stat = "identity")

```

the caption is displayed at the bottom of the figure, but I would like to display it above the figure.

解决方案

For HTML output, you may set the chunk option fig.topcaption = TRUE to place captions above figures. Below is a minimal example (it works for both html_document and bookdown's HTML output formats):

---
title: "Reprex"
output:
  html_document: null
  bookdown::html_document2: null
---

```{r, fig.cap='A caption.', fig.topcaption=TRUE}
plot(cars)
```
