TOC summary in the header of each slide - r

There is the list of possible R-Markdown templates for beamer_presentation in R-Markdown.
And most of them include a kind of a "Navigation bar" at the top (or left/right) of each slide, like that:
While I do understand how to create a TOC in R-Markdown (by providing a toc: true in the header, I cannot figure out how to add this navigation to each slide.
I also understand how to create a floating TOC for the R-Markdown for HTML format (via toc_float: true as it is described here) but still cannot figure out how to make it in a beamer format. Any hint will be appreciated.

The headline with the navigation bar is automatically inserted in every frame if you use a suitable beamer theme. The one you show in your questions is called Antibes

Empty headings in table of contents when RMarkdown contains tabs?

When making an RMarkdown containing tabs, some extra (blank) items appear in the table of contents.
Example
This generates the html doc below
---
output:
html_document:
toc: true
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
# First Tabs {.tabset .tabset-fade .tabset-pills}
Text before tabs
## First tab
Content in first tab
## Second tab
Content in second tab
#
# here is another section
Some further content.
Everything is as expected, except there's a blank line in the TOC.
What I've tried
I tried replacing the # that ends the tabbed content with </div> as described here. This causes the TOC to populate correctly, but (strangely) causes the content after the tabs to left-align (no idea why)
For ease of reproducibility, here's the code and a screengrab of the resulting HTML
---
output:
html_document:
toc: true
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
# First Tabs {.tabset .tabset-fade .tabset-pills}
Text before tabs
## First tab
Content in first tab
## Second tab
Content in second tab
</div>
# here is another section
Some further content.
As written in the comment: Just remove the single #.
There is also a workaorund, if you have have the following problem
Use TOC
Use Tabs
End tabbed region with further text under the tabbed region
Problem: Normaly use ## to end tabbed region, but this would be another header in the TOC
Solution: ## {.unlisted .unnumbered} will remove the header from TOC.
Example:
---
output:
html_document:
toc: true
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
## title {.tabset .tabset-fade}
content above tabbed region.
### tab 1
tab content 1
### tab 2
tab content 2
## {.unlisted .unnumbered}
content below tabbed region

Insert a logo in upper right corner of Rmarkdown pdf document & header

I viewed the "insert a logo in upper right corner of R markdown pdf document"topic and I managed to insert a logo in the upper right corner using this input:
pdf_document:
keep_tex: true
includes:
in_header: header.tex
But when I additionally include author: title: date: the logo disappears.
I realised, that in a document with more than one page, the logo appears from the second page onwards but not on the first page, where I included the header
How can I include the logo on the first page additional to the normal infomations as author:, titel: and so on?
Put the following in 'header.tex'
\usepackage{titling}
\pretitle{%
\begin{center}
\LARGE
\hfill \includegraphics[width=4cm,height=6cm]{logo.png}\\[\bigskipamount]
}
\posttitle{\end{center}}

R markdown anchor at the top of document

Similar to the question asked here I am trying to insert anchors in a long document so that users can easily navigate to the TOC of the document.
My code is as follows:
---
title: "Sample Document"
output:
html_document:
toc: true
theme: united
---
<a id="top"></a>
# First Section
Then I add [Go to Top](#top) wherever I want a link to go to the top of the document.
The problem I am having is that on clicking Go to Top, the page scrolls up such that First Section is at the top, not the Table of Contents (which is what I want). So the users have to scroll up again to go to TOC.
Is there any way to scroll back to the very top of the document, so that TOC is seen again on the page.
I tried to to put <a id="top"></a> before ---, but that does not work.
Any help would be much appreciated!! Thanks.
Just add you link somewhere and refers to #header...
back to top

How to end a header 3 box in rmarkdown beamer madrid presentation?

When using the Madrid beamer theme (and some others) the Header 3 is rendered as a box covering the whole section, but in markdown the header is only specified at the start. How can I specify the end of the section?
In the example below, I want the second sentence to be inside the box, but the third to be back on the white background.
Example:
---
title: "Example"
output:
beamer_presentation:
colortheme: beaver
theme: Madrid

## Slide with Box
Hello, I'm not in the box
### This is a box
And this text is in the box!
I don't want to be in the box, but I am.
Output
This works for me:
## Slide with block 2
Hello, I'm not in the block.
\begin{block}{This is a block}
And this text is in the block!
\end{block}
Hi, I'm not in the block either!
With newer versions of Pandoc (I have 2.2.3.2), you can use fenced divs to enclose a block. Did not work for me previously with 1.6.
Thus, this would work:
## Slide with Box
Hello, I'm not in the box
::: {.block}
### This is a box
And this text is in the box!
:::
I don't want to be in the box, and I am not.
::: {.block} and ::: delimit the block. See https://github.com/jgm/pandoc/issues/2957
An advantage with respect to using \begin{block} and \end{block} is that you get to use markdown within the block.

How to add table of contents in HTML output of knit /Rstudio

What are possible ways of adding table of contents in html output of knitr::knit2html()?
I am familiar with the markdownHTMLOptions solution. However the result is not the good-looking one? For me it is important to have such table of contents so that it follows the webpage while scrolling and i could possibly navigate anytime I want.
A floating table of contents is now supported by Rmarkdown! It moves with you as you scroll, you click to navigate... such an improvement :)
The directions are very good: http://rmarkdown.rstudio.com/html_document_format.html
In short, add this at the top of your rmd script, where toc stands for table of contents, and float means that it stays visible on the left as the page scrolls:
---
title: "Bla"
output:
html_document:
toc: true
toc_float: true
---
