在 RMarkdown 投影仪演示文稿中的文档类之前包含乳胶包选项

Question

我正在尝试在rmarkdown 中编译以下beamer 演示文稿。但是当它尝试渲染 rmarkdown 文档时会发生错误

! LaTeX Error: Option clash for package xcolor. 

我在网上搜索，发现我需要在\documentclass 行之前包含\PassOptionsToPackage{table}{xcolor}。 Applying options to already loaded package，另见here

如何在 RMarkdown 中做到这一点？

    ---
    title: "My report"
    output: 
    beamer_presentation:
        keep_tex: true
    header-includes: 
    - \usepackage{booktabs}
    - \usepackage{tabu}
    - \usepackage{threeparttable}
    - \usepackage{threeparttablex}
    - \usepackage[normalem]{ulem}  
    - \usepackage[table]{xcolor}
    ---


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

    ```{r positioned_table}
    dt <- mtcars[1:5, 1:6]
    kable(dt) %>%
    kable_styling("striped", full_width = F) %>%
    column_spec(5:7, bold = T) %>%
    row_spec(3:5, bold = T, color = "white", background = "#D7261E")
    ```

Answer 1

使用来自@samcarter 的非常有用的评论，我找到了确切的答案。我所需要的只是我的 rmarkdown 文档中的以下 yaml 标头：

    ---
    title: "My report"
    output: 
      beamer_presentation:
        keep_tex: true
    classoption: xcolor=table
    header-includes:
      - \usepackage{booktabs}
      - \usepackage{tabu}
      - \usepackage{threeparttable}
      - \usepackage{threeparttablex}
      - \usepackage[normalem]{ulem}
    ---

Answer 2

要使用 table xcolor 选项并打开投影仪，可以将其传递给文档类。在传统乳胶中

\documentclass[xcolor={table}]{beamer}

对于markdownhttps://bookdown.org/yihui/rmarkdown/pdf-document.html#latex-options建议on可以使用

 classoption: xcolor={table}
