r-markdown - 将官员/办公室页面上导入的图像最大化为 Word (docx)

Question

我最近尝试使用 officedown创建我的文档的 .docx 报告。在我的文档中，我从项目目录中的 \images 文件夹导入图像。

通常，当我编织文档时，我能够最大化其在页面上的位置。有谁知道如何使用 Officedown 来做到这一点？当我在 RMarkdown 中运行此代码时没有任何问题

这是我使用 Officedown 得到的结果

这就是我想要的(注意图像占据了整个页面)

我在下面添加了一个代表

knitr::opts_chunk$set(fig.align = 'center',
                      fig.cap = TRUE,
                      fig.pos = 'H',
                      fig.path = 'images/',
                      echo = FALSE,
                      warning = FALSE, 
                      message = FALSE,
                      include = TRUE,
                      out.height="100%",  out.width="100%",
                      dpi = 300)

```

```{r}
# Creating a boxplot and saving it in \images directory
plot <- ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, color = Species)) +
  geom_boxplot()
ggsave("images/plot.png",plot, width=11, height=8.5, dpi=300)

```

## Figures 

Figure \@ref(fig:boxplot) shows a boxplot that is made within the RMarkdown document. 
I want to call in an image saved from a previous R scripts which is saved 
in my `\images` directory shown in Figure \@ref(fig:plot). But notice how it 
does not take up the whole page.

Answer 1

您可以使用knitr常用参数fig.width和fig.height(英寸)。
