制造；“谢谢你”；滑入R标记

如何制作中间有“谢谢”字样的幻灯片，我尝试过：

\begin{frame}
\begin{center}
Thank You
\end {center}
\end{frame}

但它不起作用，出现了错误

当我试着做这样的事情时：

## Title
\begin{center}
Thank You
\end {center}

---

我不知道如何删除标题。

示例：

---
title: "Title"
author: "Name"
output:
  beamer_presentation:
    theme: "Singapore"
    colortheme: "seagull"
    fonttheme: "serif"

fontsize: 16pt
---


## Slide 1
text

## Slide 2
# hear I want to have a sign "Thank You" on the middle of the page, what I've tried is in my question:

\begin{frame}
\begin{center}
Thank You
\end {center}
\end{frame}

如果您只需要在没有幻灯片标题的情况下居中，只需使用

##

创建一个空标题即可，请参见以下内容：

---
title: "Title"
author: "Name"
output:
  beamer_presentation:
    theme: "Singapore"
    colortheme: "seagull"
    fonttheme: "serif"

fontsize: 16pt
---


## Slide 1
text

## Slide 2

##
\begin{center}
Thank You
\end {center}

希望这有帮助
