在 r 中自定义 rticles::elsevier_article 文档 class 的输出

Question

我试图在 elsevier_article 中设置边距，但收效甚微。 This post 建议使用几何图形设置边距，但我收到以下错误：

! LaTeX Error: Option clash for package geometry.

我还尝试在序言中添加以下乳胶命令，但 none 确实更改了输出 PDF 中的边距：

header-includes:
  - \PassOptionsToPackage{left=2.5cm,right=2.5cm,top=2.5cm,bottom=2.5cm}{geometry}

header-includes:
  - \PassOptionsToPackage{margin=2.5cm}{geometry}

我需要在页面的两边留出 2.5 厘米。下面是可以使用的东西。它只是可以从 Rstudio 访问的默认模板（我删除了一些不需要的东西）：

Answer 1

header-includes来不及使用\PassOptionsToPackage{...}，这个宏需要在documentclass之前使用，这在rmarkdown中有点难做。

相反，您可以使用 \geometry{...} 在程序包加载后更改设置。
