使用Knitr并排插入png图像 [英] insert side by side png images using knitr

问题描述

在创建html文档时，如何将计算机中的png文件插入到rstudio中?

How can I insert side by side png files from my computer into rstudio when creating an html document?

以下方法效果很好(图)

The following works well (plots)

```{r, echo=FALSE,fig.width=4, fig.show='hold'}
 plot(cars)
plot(rnorm(100))
```

但是对于来自路径的图像，仅显示最后一张图像

But for images from a path, only the last image is displayed

 ```{r fig.width=3, fig.show='hold'}
   library(png)
  img <- readPNG("C:/path to my picture/picture.png")
  grid.raster(img)

  img2 <- readPNG("C:/path to my picture/picture2.png")
  grid.raster(img2)
  ```

推荐答案

您应该学习Markdown的语法(确实需要大约五分钟).该解决方案甚至根本不涉及R:

You should learn the syntax of Markdown (really, you need about five minutes). The solution does not even involve R at all:

![](path/to/picture.png) ![](path/to/picture2.png)

顺便说一句，您最好避免使用绝对路径.使用相对路径(相对于Rmd文件).

BTW, you'd better avoid absolute paths. Use relative paths (relative to your Rmd file).
