使用Knitr从R块内以编程方式将图像包含在.md文档中 [英] include images programmatically in .md document from within R chunk using knitr

问题描述

我想以编程方式在.Rmd markdown文档中包含很多图像.

I want to programmatically include a lot of images in my .Rmd markdown document. Something like

```{r echo=FALSE}
cat("![](myfile_1.png)")
```

将不起作用，因为最终的.md输出为

will not work, as the resulting .md output is

```
## ![](myfile_1.png)
```

我需要摆脱代码标签```和前导##. 是否可以选择直接从R块中插入降价代码?

I would need to get rid of the code tags ``` and the leading ##. Is there an option to directly inject markdown code from within the R chunk?

BTY:同样的问题也适用于HTML.在这里，从R块中注入HTML代码也会很有帮助.

BTY: The same issue applies to HTML as well. Here also a HTML code injection from within an R chunk would be really helpful.

推荐答案

使用results ='asis'意味着您不必弄乱钩子，注释等，因为结果不是代码，而是markdown(或其他任何标记)输出格式恰好是)

Using results ='asis' means that you don't have to mess with the hooks, comments etc as the results are not considered code, but markdown (or whatever the output format happens to be)

```{r myfile-1-plot, echo = F, results = 'asis'}
cat('\n![This is myfile_1.png](myfile1.png)\n')
```

会导致

![This is myfile_1.png](myfile1.png)

请注意，我用新的行标记将输出文本包裹起来，以确保它在单独的行上.

Note that I wrapped the output text with new line markers to ensure that it is on a separate line.
