使用 Rmarkdown 制作结论幻灯片放映机

Question

我正在尝试使用 Rmarkdown 在 beamer 中制作类似这样的结论幻灯片。但是，我想在幻灯片左侧制作蓝色矩形，并在其后跟灰色矩形。问题是我无法制作这两个矩形。框架标题仍然存在，即使我尝试在 YAML 标头中使用，也无法将其删除：

- \makeatletter
- \def\ps@navigation@conclusion{\setbeamertemplate{headline}{}\setbeamertemplate{footline}{}\setbeamercolor{frametitle}{bg=white, fg = white}\@nameuse{ps@navigation}}
- \makeatother

\thispagestyle{navigation@conclusion}并在右侧幻灯片上使用。

矩形也不想从幻灯片的左下角开始。我现在正在使用此代码。矩形的颜色应该是我定义为 BlueM 的蓝色，但这也不起作用。

### Conclusion
\thispagestyle{navigation@conclusion}

\begin{tikzpicture}
\filldraw[color=red!60, fill=red!5, very thick](-1,0) rectangle (5,20);
\end{tikzpicture}

我知道我可以用 来制作点，\draw[fill=white] (5.8,2) circle (0.6) node[align=center]{\includegraphics[width=0.07\textwidth]{FIGURE}};但我不知道如何让它们从灰色矩形的末端开始。另外，如何将文本与点对齐对我来说也是一个问题。

使用时\draw[fill=white] (5.8,2) circle (0.6) node[align=center]{\includegraphics[width=0.07\textwidth]{FIGURE}}。图为

有人能帮我吗？

这是我现在正在使用的主题：

如果您使用该remember picture选项tikzpicture，您可以根据页面定位矩形等：

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{positioning}

\begin{document}

\begin{frame}
\begin{tikzpicture}[remember picture, overlay]
\fill[white] (current page.south west) rectangle (current page.north east);
\fill[blue!40!black] (current page.south) rectangle (current page.north east);
\fill[lightgray!30] (current page.south) rectangle ([xshift=1.25cm]current page.north);

% red circle
\node[fill=red,draw=white,circle,font=\color{white}\Huge,ultra thick] (1) at ([yshift=-2cm]current page.north) {1};
\node[left=of 1,anchor=east,text width=.3\textwidth,align=left] {\textbf{Conclusions}\\some other text};

% blue circle
\node[fill=blue!40!black,draw=white,circle,font=\color{white}\Huge,ultra thick,below=of 1] (2) {2};
\node[left=of 2,anchor=east,text width=.3\textwidth,align=left] {\textbf{Conclusions}\\some other text};
\end{tikzpicture}
\end{frame}
    
\end{document}
