将 HTML 转换为 R Markdown

有没有办法转换html文件，例如https://cran.r-project.org/web/packages/tidytext/vignettes/tidytext.html，并将其转换为可执行的 R Markdown 文件（rmd）？

这是我使用的解决方案：

• 将 .html 转换为 .md ：

pandoc ./test.html -o test.md

• 将 .md 重命名为 .rmd

mv test.md test.rmd

• 对代码进行后处理以组织块和段落

# chunks r marker: replace ' {\.sourceCode \.r}' by '{r}'
sed -i 's/ {\.sourceCode \.r/{r/' test.rmd
# delete lines beginning wit ':::'
sed -i '/^:::/d' test.rmd
# delete lines beginning '![](data:image' (html plot)
sed -i '/^\!\[\](data:image/d' test.rmd
# delete paragraph separator lines
sed -i '/^=====/d' test.rmd
sed -i '/^-----/d' test.rmd
# replace paragraph marks
#'[1]{.header-section-number}' by '#'
sed -i 's/\[[0-9]\+\]{\.header-section-number}/#/' test.rmd
#'[1.1]{.header-section-number}' by '##'
sed -i 's/\[[0-9]\+\.[0-9]\+\]{\.header-section-number}/##/' test.rmd
#'[1.1.1]{.header-section-number}' by '###'
sed -i 's/\[[0-9]\+\.[0-9]\+\\.[0-9]\+]{\.header-section-number}/###/' test.rmd

• 添加 YAML 标头

echo "$(echo -e "\n" | cat - test.rmd)" > test.rmd
echo "$(echo '---' | cat - test.rmd)" > test.rmd
echo "$(echo 'title: '\"'test'\" | cat - test.rmd)" > test.rmd
echo "$(echo '---' | cat - test.rmd)" > test.rmd

当然，您可以将这些行放在 .sh 中以简化任务
