Beamer Rmarkdown: no page number for specific slides - r-markdown

I have some slides produced in Rmarkdown. I just want the slides after the conclusion not to have numbers. I tried all the solutions that are posted in this website and similar (e.g.: \appendix
\setcounter{framenumber}{2}, \pagenumbering{gobble}, etc.) but they don't work. Also this Rbeamer for back-up slides doesn't work in my case and I don't understand why.
This is my framework:
---
title: "Title"
subtitle: "Subtitle"
date: "xx/xx/2020"
output:
beamer_presentation:
theme: "Boadilla"
colortheme: "orchid"
header-includes:
- \usepackage{tikz}
- \usetikzlibrary{decorations.pathreplacing,calc,tikzmark}
- \usetikzlibrary{tikzmark,fit,shapes.geometric}
- \usepackage{lipsum}
- \usepackage{lmodern}
- \usepackage{tcolorbox}
- \usepackage{appendixnumberbeamer}
---
## Title 1
Text 1
---
## Title 2
Text 2
---
## Conclusion
concluding
---
## NO PAGE NUMBER
I don't want page numbers here
Thanks a lot!

slide presentation change language of top title

I would like to get Inhalt instead of Contents in the lower left corner of a slide presentation.
I tried

## R Markdown
When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document.
## Slide with Bullets
- Bullet 1
- Bullet 2
- Bullet 3
but this did not work.
The lower left Contents could be changed to Inhalts using javascript code (sort of Brute-force way)
presentation.Rmd

title: "Untitled"
author: "Erich Neuwirth"
date: "2022-09-28"

everything works file.
lang: de changes titles and similarar things to German. It just does not replace the Content link in the lower left corner.

Multiple authors in Rmarkdown ioslides_presentation without Hyphen sign

I want to add two authors in my Rmarkdown presentation using ioslides_presentation as the output. This is what I tried:
---
title: "Sample title"
author:
- "Author1"
- "Author2"
output: ioslides_presentation
---
However it gives me an extra Hyphen sign for both authors:
If I change the output to slidy_presentation or revealjs::revealjs_presentation it'll work fine. It's only the problem with ioslides_presentation.
Any help is appreciated.

Insert navigation bar in Beamer presentation with Rmarkdown

I am trying to make Beamer presentation in R Markdown, you can see how code begin below :
---
title: "Test presentation"
author:
- Loana
institute:
- Supervised by
- University
date: Academic year 2017-2018
output:
beamer_presentation:
incremental: false
theme: "Frankfurt"
colortheme: "beaver"
toc: true
slide_level: 5
keep_tex: true
header-includes:
- \AtBeginSubsection{}
---
This code give output like pic below
But my intention is to have navigation bar in right corner of slide, so can anybody help me how to do this ?
Is the following your desired output?
If so, create a file header.tex with the following contents (taken from https://tex.stackexchange.com/a/35637/181010)
\setbeamertemplate{navigation symbols}{}
\makeatletter
\setbeamertemplate{footline}
{%
\pgfuseshading{beamer#barshade}%
\ifbeamer#sb#subsection%
\vskip-9.75ex%
\else%
\vskip-7ex%
\fi%
\begin{beamercolorbox}[ignorebg,ht=2.25ex,dp=3.75ex]{section in head/foot}
\insertnavigation{\paperwidth}
\end{beamercolorbox}%
\ifbeamer#sb#subsection%
\begin{beamercolorbox}[ignorebg,ht=2.125ex,dp=1.125ex,%
leftskip=.3cm,rightskip=.3cm plus1fil]{subsection in head/foot}
\usebeamerfont{subsection in head/foot}\insertsubsectionhead
\end{beamercolorbox}%
\fi%
}%
\setbeamertemplate{headline}{%
\hskip1em\usebeamercolor[fg]{navigation symbols dimmed}%
}
\makeatother
Then add the header to the yaml of your .Rmd as:
---
title: "Test presentation"
author:
- Loana
institute:
- Supervised by
- University
date: Academic year 2017-2018
output:
beamer_presentation:
incremental: false
theme: "Frankfurt"
colortheme: "beaver"
toc: true
slide_level: 5
keep_tex: true
header-includes:
- \AtBeginSubsection{}
- \input{header.tex}

Rmarkdown beamer slides does not show itemise bullets

I was trying to write create some beamer slides in Rmarkdown. Since the beamer slides would need to include some Chinese characters, I have to specify xelatex as the latex engine.
However, recently I found that the xelatex engine has a problem (the problem was not here a month ago): When using xelatex as the latex engine, the itemise bullets in beamer slides disappeared.
Does anyone know how to resolve this issue?
Below is a minimum working example:
---
title: trial doc
institute: |
| Department trial
| trial Education
Date: "17 October 2020"
output:
beamer_presentation:
theme: "CambridgeUS"
colortheme: "dolphin"
slide_level: 3
latex_engine: xelatex
df_print: kable
classoption: "aspectratio=169"
fontsize: 10pt
mainfont: Times New Roman
header-includes:
- \setbeamercolor{frametitle}{bg=white}
- \usepackage{ctex}
- \AtBeginSubsection{}
- \AtBeginSection{}
- \setbeamerfont{frametitle}{series=\bfseries}
- \AtBeginDocument{\title[xxx]{xxxxx}}
- \AtBeginDocument{\institute[xxxxx]{\\Department of xxx\\xxx}}
- \AtBeginDocument{\author[xxxxxx]{XXX}}
---
\frametitle{Outline}
\tableofcontents
# 欢迎
\frametitle{\textbf{Welcome}}
some text
some Chinese text 你好
trying to itemize:
- Hello
- subitem
trying some numbered list:
1. hello
2. hello
And the output I get is as below:
Output from the code above
When I try using pdflatex as the latex engine (in which case I cannot use the ctex package and cannot include Chinese characters in my beamer slides), the itemize and numbered list works perfectly.
Really appreciate if someone can help me with this!
As provided by #samcarter_is_at_topanswers.xyz above, I solved this problem by following the steps in github.com/pgf-tikz/pgf/issues/928#issuecomment-700690532.

Automatically number sections in RMarkdown

I am trying to create a report in R markdown that has sections ordered
Section 1 Header
1.1 sub section 1
1.2 sub section 3
Section 2 Header
2.1
2.2 sub section
2.2.1 another sub section
Is there a way get R markdown to generate an ordered list like this?
Add the option number_sections: true to your YAML header:
---
title: "My Report"
output:
html_document:
number_sections: true
---
# Main Section
## 2nd Level
### 3rd Level
And voilá, your sections are numbered:
