删除 Markdown 默认代码

Question

在 RStudio 中，每当我创建一个新的 Markdown 时，它总是有默认代码。我该如何删除它？

这是显示的代码。

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

## R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```{r cars}
summary(cars)
```

## Including Plots

You can also embed plots, for example:

```{r pressure, echo=FALSE}
plot(pressure)
```

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.

每次创建Rmd文件时，Rstudio都会打开一个Rmd模板：

https://github.com/rstudio/rstudio/blob/822e558c7a274de464f992f69e3acee2fde5ab04/src/cpp/session/modules/SessionRMarkdown.R

# given a path to a folder on disk, return information about the R Markdown
# template in that folder.
.rs.addFunction("getTemplateDetails", function(path) {
   # check for required files
   templateYaml <- file.path(path, "template.yaml")
   skeletonPath <- file.path(path, "skeleton")
   if (!file.exists(templateYaml))
      return(NULL)
   if (!file.exists(file.path(skeletonPath, "skeleton.Rmd")))
      return(NULL)

   # load template details from YAML
   templateDetails <- yaml::yaml.load_file(templateYaml)

   # enforce create_dir if there are multiple files in /skeleton/
   if (length(list.files(skeletonPath)) > 1) 
      templateDetails$create_dir <- TRUE

   templateDetails
})

因此最简单的解决方案是：

转到 xxx\RStudio\resources\templates 文件夹，您的安装了 Rstudio
打开r_markdown_v2.Rmd文件，然后删除一切
保存

现在，每次打开 rmarkdown 时，您都可以只看到 yaml 部分。
