将 Posterdown Package (R) 中的 HTML 文件渲染为 PDF

Question

我正在尝试使用posterdownRMarkdown ( https://pythonawesome.com/use-rmarkdown-to-generate-pdf-conference-posters-via-html-or-latex/ ) 中的包来生成一个漂亮的 PDF 文件。我注意到安装包后默认模板会生成为 HTML 文件。有什么方法可以将其设置为生成 PDF 文件而不是 HTML 文件吗？

此外，是否可以将页眉和标题中的默认颜色（绿色）自定义为我选择的 HTML 颜色代码？

这是默认的 YAML

Answer 1

您可以使用YAML或内联 CSS控制颜色，您需要添加knit: pagedown::chrome_print到 YAML 以打印到 PDF 并保留 CSS 代码。self_contained: TRUE我还出于习惯更改了代码。当我运行下面的代码时，我的posterdown标题颜色发生了变化，并且它在我的默认 PDF 查看器中打开，因为它现在是.PDF
