"自动调整大图以适合 rmarkdown 的页面 pdf 输出"

Question

I am having issues when knitting my rmarkdown file to PDF with large plots. The plots get cut when producing the PDF file.

## Large Plot

```{r}
library(meta)

data(Fleiss93)

##
m <- metabin(event.e, n.e, event.c, n.c,
              data = Fleiss93, studlab = study,
              sm = "RR", method = "I")

forest(m)
```

Answer 1

To change default settings, put the following code chunk early in your document:

```{r include = FALSE}
knitr::opts_chunk$set(fig.height = 9, fig.width = 7)
```
