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

问题描述

我正在尝试使用 RMarkdown (https://pythonawesome.com/use-rmarkdown-to-generate-pdf-conference-posters-via-html-or-latex/) 中的 posterdown 包来生成一个不错的 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为 PDF 而不是 HTML 文件吗？

此外，有没有办法将标题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

TIA！

解决方法

您可以使用 YAML 或内联 CSS 控制颜色，您需要将 knit: pagedown::chrome_print 添加到您的 YAML 以打印为 PDF 并保留 CSS 代码。我也出于习惯将代码更改为 self_contained: TRUE。当我运行下面的代码时，我改变了 posterdown 标题颜色，它在我的默认 PDF 查看器中打开，因为它现在是 .PDF
