I want to produce a beamer presentation from a RMarkdown file.
I am in this case using this beautiful template: https://github.com/matze/mtheme
How in markdown can you specify that you want to insert, not a "normal" slide, by a special one, such as an appendix slide, or a standout slide?
This template contains a standout slide that I would like to use as final slide as they do in their demo slides (http://mirrors.standaloneinstaller.com/ctan/macros/latex/contrib/beamer-contrib/themes/metropolis/demo/demo.pdf)
In beamer, I would do:
\begin{frame}[standout]
Questions?
\end{frame}
What is the equivalent in Markdown?
Setting frame options is pretty straight forward:
---
title: "Untitled"
output: beamer_presentation
theme: "metropolis"
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```
## {.standout}

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$set(echo = FALSE)
```
## Slide with Bullets
- Bullet 1
- Bullet 2
- Bullet 3
## Slide with R Output
```{r cars, echo = TRUE}
summary(cars)
```
More about this can be found in Yihui Xie et al. (2021) R Markdown: The Definitive Guide, Section 4.4.
Tested with RStudio Version 1.4.1714 and Powerpoint 2016.
I'm trying to knit an HTML document from RMarkdown, and hide the section from both the Table of Contents (ToC) and body of the output (HTML file), while while still knitting (executing) all of the code and contents.
I'm not looking to hide just the code chunk - this can be done through echo = FALSE.
I tried using the {.hidden} option meant for flexdashboards but it only partially solves the problem, i.e. the whole section (called # The section I want to hide in the example below) disappears from the HMTL output itself, but not the table of contents.
Code example:
---
output:
html_document:
df_print: kable
fig_height: 2
fig_width: 2
number_sections: yes
toc: yes
toc_float: yes
editor_options:
chunk_output_type: console
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE,
warning = FALSE,
message = FALSE,
cache = FALSE,
dpi = 75,
comment = '')
```
# R Markdown
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>.
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 cars}
summary(cars)
```
# Including Plots
You can also embed plots, for example:
```{r pressure, echo=FALSE}
plot(pressure)
```
Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
# The section I want to hide {.hidden}
Super-secret text (section content I don't want to show).
```{r}
sumCars <- summary(cars)
```
# This the section I want to show again
```{r}
sumCars[1,]
```
Output:
HTML output
How can I hide the document section while still knitting?
You can use arbitrary css in markdown when exporting to html. Here is an example:
---
title: "Untitled"
output: html_document
---
# One
Hello!
# Two
<style>
#two {
display: none;
}
</style>
```{r}
x <- 1:10
```
# Three
```{r}
plot(x)
```
The unlisted class ensures that a heading is not included in the table of contents, and hidden will hide a section in HTML output. Therefore, the following should work:
# The section I want to hide {.hidden .unlisted}
a header is created for pages 2+ with fancyhdr but how can you make the same header also appear on the first page?
here is the rmarkdown:
---
title: "Untitled"
classoption: landscape
output:
pdf_document:
number_sections: false
dev: pdf
keep_tex: false
toc: yes
header-includes:
- \usepackage{fancyhdr}
- \pagestyle{fancy}
- \fancyhead[C]{center text}
- \fancyhead[R]{right text}
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
Include \thispagestyle{fancy} in the beginning of your document (e.g. just after the yaml header) to make the first page fancy.
Edit to address your comment
If you want to have different center text in the first page you can have use if when you define \fancyhead
\fancyhead[C]{\ifnum\value{page}>1 center text \else \fi}
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 writing a beamer presentation in rmarkdown and converting it to pdf with knitr. I want to define sections at the header1 level, e.g. # Introduction, and then have a slide titled something else e.g. ## Introducing my brilliant research. Having the header1 level define sections is nice as the names of the sections can be displayed in the slide header in certain beamer themes, and this is why I include it.
But I do not want rmarkdown to insert a slide that simply says the name of the section between sections, which at the moment it is doing. Is there a way to not print a slide with the section name between sections? I thought slide_level would control this behavior but it does not seem to (or perhaps I am using it wrong).
A minimal reproducible example of my problem can be obtained with this code:
---
title: "Test Pres"
author: "Professor Genius Researcher"
date: "24 February 2017"
output:
beamer_presentation:
slide_level: 2
theme: "Singapore"
colortheme: "rose"
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```

At the moment, this code produces slides that say Markdown Intro, Using Bullets, and Including Chunks. I would like those slides labeling the sections omitted. Is this possible?
Create a new Latex template where you remove this part from the preamble:
\AtBeginSection[]
{
....
}
Place this latex template in the same folder as your .Rmd file and refer to it in the Rmd Yaml front matter using template: mytemplate.tex as explained here.
