I have a simple test .Rmd script which I am using to generate a PDF file with the rmarkdown render function.
When I set the toc to be true, the second PDF page is a blank white page and I would expect to see 'Slide With Bullets' and 'Slide with R Code and Output' to be in there.
Does anyone know how to format the slide titles so that they appear in the table of contents?
---
title: "test"
author: "test"
date: '2015-10-29'
output: beamer_presentation
toc: true
---
## Slide with Bullets
- Bullet 1
- Bullet 2
- Bullet 3
## Slide with R Code and Output
```{r}
summary(cars)
```
According to the documentation toc only works with level 1 headings. So the code below will create a table of contents to the title slide. I can't get it to work with slides that contain content though. Maybe this is how the table of contents is designed to work???

title: "Untitled"
output:
beamer_presentation:
toc: yes

# A Title Slide:
## Slide with Bullets
- Bullet 1
- Bullet 2
- Bullet 3
## Slide with R Code and Output
```{r}
summary(cars)
```

I'm using R markdown to create a presentation, and I would really like to add a custom background on my opening slide and second slide. Currently, I have my potential themes on a separate PowerPoint document. Is there any way to add backgrounds like that?
Thanks!
To add a custom background, one can create a powerpoint template, e.g. my-styles.pptx where the background image is placed at the slide master.
Then create an Rmarkdown file like follows and place it in the same folder:
---
title: "Fancy Slides"
author: "Creative Author"
date: "2021-06-09"
output:
powerpoint_presentation:
reference_doc: my-styles.pptx
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```
## Slide with Bullets
- Bullet 1
- Bullet 2
- Bullet 3
## Slide with R Output
```{r cars, echo = TRUE}
summary(cars)
```
More about this can be found in Yihui Xie et al. (2021) R Markdown: The Definitive Guide, Section 4.4.
Tested with RStudio Version 1.4.1714 and Powerpoint 2016.
In a LaTex beamer presentation generated with rmarkdown::beamer_presentation, how can I remove the slide numbers for specific slides?
Since the slides contain plots and tables generated by R-markdown, plain LaTex approaches like the attempt below likely won't work.
``` {=latex}
\begin{frame}[noframenumbering]{Frame name}
Frame without slide number but with Rmd-generated tables and plots.
- All other frames still have slide numbers.
\end{frame}
```
The noframenumbering option is not what you think it is. It is to exclude the frame from being counted.
To remove the footline with the page numbering, you can use the plain option:
---
output:
bookdown::pdf_book:
base_format: rmarkdown::beamer_presentation
theme: "THEMENAME"
slide_level: 2
keep_tex: true
---
## Slide 1 {.noframenumbering}
test
## Slide 2 {.plain}
test
## Slide 3
test
I'm looking for a way to evaluate code in a incremental way in R markdown presentation. I don't need to use any specific format - it can be anything that works and is flexible (rpres, ion, revealjs, etc.)
I'll use these presentation in class for my students and would like to make them type code in their R Console first and then compare our outputs.
So far I came up with one solution using revealjs with slide_level header
---
title: "Test presentation"
output: revealjs::revealjs_presentation
slide_level: 2
---
# Level 1 horizontal main slide
Some text
## Level 2 vertical slide with R Code
```{r eval=FALSE}
summary(cars)
```
## Level 2 vertical slide with R output
```{r echo=FALSE}
summary(cars)
```
Anything easier and less time consuming would be great.
I know the question is a bit old but you can use the incremental option for example with ioslides. That way you don't have to change slide but you can print step by step first the text then the code and then the result.
example code:
---
title: "Test presentation"
output:
ioslides_presentation:
incremental: yes
---
## Slide 1
- Some text
- Level 2 just the code
```{r eval=FALSE}
summary(cars)
```
- Level 2 just the output
```{r echo=FALSE}
summary(cars)
```
I am using rmarkdown to make beamer presentations in RStudio. I would want to get slide tickers on the top of presentation. Dresden theme should support those tickersDresden
So is it possible to get those tickers by using rmarkdown? When I knit pdf I get presentation without slide tickers.
Example code:
---
title: "Example"
output: beamer_presentation
theme: Dresden

# R Markdown
This is an R Markdown presentation. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.
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
# Slide with R Code and Output
```{r}
summary(cars)
```
# Slide with Plot
```{r, echo=FALSE}
plot(cars)
```
I think the slide_level option might be what you are looking for:
The slide_level option defines the heading level that defines individual slides. By default this is the highest header level in the hierarchy that is followed immediately by content, and not another header, somewhere in the document. This default can be overridden by specifying an explicit slide_level
documentation source
For example with the slide_level: 2:
---
title: "Example"
output:
beamer_presentation:
slide_level: 2
theme: Dresden
---
gives you the following output
However you need to provide a lower level of the heading for the slide title, e.g.

I am using RStudio for writing markdown documents and want to add Table of Contents (TOC) at top of the documents so that the user could click the relevant section for reading. There were some relevant examples on rpubs but now I can't seem to find them. Please note that I don't use pandoc and am quite new to Rmd & knitr. Is there any way to add TOCs without using pandoc? If using pandoc is must then which functions are relevant?
EDIT
Here's a small sample page:
---
title: "Sample Document"
output:
html_document:
toc: true
theme: united
---
Header 1
---------------
This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.
## Header 2
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. You can embed an R code chunk like this:
```{r}
summary(cars)
```
You can also embed plots, for example:
```{r, echo=FALSE}
plot(cars)
```
### Header 3
Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
I tried running this in RStudio v 0.98.864 and it worked! but sadly it didn't work on 0.98.501 and 0.98.507. I am working on my thesis in 0.98.501 and after updating RStudio, some of my analyses didn't work. So, I reverted back to 0.98.501.
What should I do now? I really want TOCs but without harming the outputs of other analyses.
The syntax is
---
title: "Sample Document"
output:
html_document:
toc: true
theme: united
---
in the documentation. Make sure this is at the beginning of your document. Also make sure your document actually has headers otherwise R can't tell what you want in the table of contents.
Syntax with more options:
---
title: "Planets"
author: "Manoj Kumar"
date: "`r format(Sys.time(), '%B %d, %Y')`"
output:
html_document:
toc: true # table of content true
toc_depth: 3 # upto three depths of headings (specified by #, ## and ###)
number_sections: true ## if you want number sections at each table header
theme: united # many options for theme, this one is my favorite.
highlight: tango # specifies the syntax highlighting style
css: my.css # you can add your custom css, should be in same folder
---
If you are using pdf_document, you might want to add table of contents in a new page, which toc: true does not allow. It puts the table of contents right after the document title, author and date--because it is in yaml.
If you want to have it in a new page, you have to use some latex language. Here is what I did.
---
title: \vspace{3.5in}"Title"
author: "Name"
date: "`r Sys.Date()`"
output:
pdf_document:
fig_caption: true
number_sections: true
---
\newpage # adds new page after title
\tableofcontents # adds table of contents
\listoffigures
\listoftables
\newpage
So, after yaml (the chunk between ---), I added a new page using \newpage, then a table of contents using \tableofcontents, a list of figures using \listoffigures, a list of tables \listoftables, and a new page before everything else.
Note, \vspace{3in} in the title adds vertical space of 3 inch from the top before printing yaml (title, etc.).
