I am trying to convert a .Rmd file to .md (output: md_document), but the title does not show up on the rendered file.
The title does show up when I try to render the same file as an .html file (output: html_document).
Title shows up on rendered document:
---
title: "Test"
output: html_document
---
```{r}
head(cars)
```
Title does not show up on rendered document:
---
title: "Test"
output: md_document
---
```{r}
head(cars)
```
rmarkdown::render(my_file)
Any ideas why?
I am using RStudio 0.98.1091 and R 3.1.2 on a Mac 10.9.5.
The code in between -- gets interpreted, as my references are rendered with the following piece of code:
---
title: "Test"
output: md_document
bibliography: ~/mybib.bib
---
This is a test where I cite [#post1, #post2]
The interesting thing is that when I ask for both the html and md files to be generated, the title shows up on the .md file:
---
title: "Test"
output:
html_document:
keep_md: yes
---
Shouldn't the output of keep_md: yes be the same as output: md_document?
Markdown does not have such a concept as "title". HTML has the <title> tag (and Pandoc also puts the title in <h1> for the HTML output from Markdown so you can see it from the HTML body), and LaTeX has the \title{} command. It is not unexpected to me that the YAML metadata (including the title info) is not reflected in the Markdown output.

I'm using R markdown to make a beamer presentation.
When I try to include an error message output from R on the slide it goes off the page.
Here is my code:
---
title: "Untitled"
author: "John Smith"
date: '2022-04-29'
output: beamer_presentation
---
This error message goes off the page
```{r cars, echo = TRUE, error=TRUE}
summary(carrrrrrrrrrrrrrrrs)
```
And, this is what the slides look like:
How do I keep the code on the page, either by putting it on multiple lines or reducing font size?
You can use the same technique as in Change representation (background-color & frame) of chunks in RMarkdown (with Beamer-Presentations) to redefine the verbatim environment in such a way that it uses the listings package. The listings package then allows you to both add line breaks and adjust the font size to your liking:
---
title: "Untitled"
author: "John Smith"
date: '2022-04-29'
output:
beamer_presentation:
keep_tex: true
header-includes:
- \let\verbatim\undefined
- \let\verbatimend\undefined
- \usepackage{listings}
- \lstnewenvironment{verbatim}{\lstset{breaklines=true,basicstyle=\ttfamily\footnotesize}}{}
---
This error message goes off the page
```{r cars, echo = TRUE, error=TRUE}
summary(carrrrrrrrrrrrrrrrs)
```
I need to update the color and font of the header (only header) in a R Markdown PDF file. I have found recourses on how to do this for the whole document, but can't find an answer for changing the headers only.
Thank you kindly!

title: "Untitled"
output: pdf_document

Simplified version of the solution provided by Grada Gukovic:
You can add simple LaTeX statements to your document via the YAML header header-includes, e.g.:
---
title: "Untitled"
output: pdf_document
header-includes:
- \usepackage{sectsty}
- \allsectionsfont{\color{cyan}}
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

Result:
This is most useful for small additions like the one seen here. If you want to add more than a few lines of LaTeX code it is often easier to save them to an external file, say preamble.tex and include that via
---
output:
pdf_document:
includes:
in_header: preamble.tex
---
Other possible places are before_body and after_body, c.f. ?rmarkdown::includes.
There is no option to do this in rmarkdown::pdf_document. You can do this by modifying the .tex template being used using the sectsty package for latex.
For example the following changes the color of all headers to cyan:
Download the default latex template from here:
tex template
Open the template in Notepad and add the following lines on an appropriate place in the document preamble(I have them as lines nr. 200 and 201):
\usepackage{sectsty}
\allsectionsfont{\color{cyan}}
Save the modified file with the extension .tex (my file is called "Cyansections.tex") and put it in R's working directory.
Modify the header of the .rmd document:
---
title: "Untitled"
output:
pdf_document:
template: Cyansections.tex
---
If you want a different color or font consult this answer
and sectsty's manual Especially section 4 of the manual for chanhing fonts
How is it possible to align the title page of my Rmarkdown beamer presentation to the LEFT instead of the default center?
Example , default is center:
---
title: "Untitled"
author: "S SS"
date: "2/4/2018"
output: beamer_presentation
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```
## R Markdown
This is an R Markdown presentation. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.
When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document.
You can switch to a left aligned title page by using
\setbeamertemplate{title page}[default][left]
To use this in rmarkdown, place this line in a file called preamble.tex and use
---
title: "Untitled"
author: "S SS"
date: "2/4/2018"
output:
beamer_presentation:
includes:
in_header: preamble.tex
---
test
Edit:
with an up-to-date version of markdown, you can also directly do
---
title: "Untitled"
author: "S SS"
date: "2/4/2018"
output:
beamer_presentation
header-includes:
- \setbeamertemplate{title page}[default][left]
---
test
Here's a hack until someone comes along with a better answer: We'll dispense with a standard beamer title slide and just format the first slide as if it were a title slide:
---
output: beamer_presentation
header-includes:
- \usepackage{color}
---
\color{blue}
\LARGE{\textbf{This is the title}}
\color{black}
\vspace{0.2cm}
\large{Author Name}
\large{February 4, 2018}
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```

I wrote my own titlepage and it is loaded via an include in the R-markdown file. However, this conflicts with the pandoc title. I am trying to find settings in the R markdown yaml header such that pandoc does not insert the following code snipped into the tex-file.
% Create subtitle command for use in maketitle
\newcommand{\subtitle}[1]{
\posttitle{
\begin{center}\large#1\end{center}
}
}
\setlength{\droptitle}{-2em}
\title{}
\pretitle{\vspace{\droptitle}}
\posttitle{}
\author{}
\preauthor{}\postauthor{}
\date{}
\predate{}\postdate{}
There is no clear indication in the pandoc documents or the r markdown guidelines how to disable the title generation. Any help would be appreciated.
Update: In particular, I am looking for solutions that allow me to keep creating my title page with the \maketitle command. That is why I focussed on this particular code snipped that I want to get rid of.
I also use my own title page with rmarkdown documents for latex/pdf outputs. To remove the title, you can add the following command in a text file called with in_header :
\AtBeginDocument{\let\maketitle\relax}
A reproductible example with the header.tex file built directly within the Rmd document:
---
title: "RMarkdown No title Test"
author: "StatnMap"
date: "July 30, 2017"
output:
pdf_document:
includes:
in_header: header.tex
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
```{r rm_title_page, echo=FALSE}
head <- cat('
\\AtBeginDocument{\\let\\maketitle\\relax}
', file = "header.tex")
```
# Title 1
**Some text**
# Title 2
**Some text**
Using compact-title: false in the YAML works.
---
title: "This title is not compact"
author: "Test"
date: "2019 May 10"
output: pdf_document
compact-title: false
---
I had the same problem today. Here's what I did. (Maybe I'll update the solution when I come up with something better.)
The solution is dumb but useful. I can't set an arbitrary space between the lines now, because I used \newline.
---
title: "\\huge My Smart Title"
author: "\\newline \\Large My Smart Author"
date: "\\newline \\Large 2018-12-25"
output:
pdf_document:
includes:
in_header: preamble.tex
latex_engine: xelatex
---
Below are the outputs before and after the solution.
BEFORE:
AFTER:
Note:
You may be confused about the different sizes of the "author" and the "date" in the two pictures above, if you don't know that the fontsize of the "author" and the "date" is \large instead of \Large by default.

I am attempting to create an rmarkdown document. I have finally figured out a way to approach this, although it has taken quite some time. The last thing I would like to be able to do is to add an image to the title page of my pdf document.
The trouble I have is that my title page is defined by the top section of YAML. Below is the contents of my example.Rmd file. I use the Knit PDF button in RStudio to turn it into a PDF.
---
title: "This is a my document"
author: "Prepared by: Dan Wilson"
date: '`r paste("Date:",Sys.Date())`'
mainfont: Roboto Light
fontsize: 12pt
documentclass: report
output:
pdf_document:
latex_engine: xelatex
highlight: tango

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)
```
Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
If anyone has some tips that would allow me to put an image (logo.png) above my title that would be great.
Based on the previous solution, the following code does not require an auxiliary header.tex file. All contents are contained in the .Rmd file. The LaTeX commands are instead defined in a header-includes block in the YAML header. More info can be found here.
Replace my_graphic.png below with your local graphic file.
---
title: "A title page image should be above me"
header-includes:
- \usepackage{titling}
- \pretitle{\begin{center}\LARGE\includegraphics[width=12cm]{my_graphic.png}\\[\bigskipamount]}
- \posttitle{\end{center}}
output:
pdf_document:
toc: true
---
\newpage
# Section 1
Some text.
I was able to solve this using LaTeX package titling
---
title: "Untitled"
author: "Name"
date: "September 19, 2015"
output:
pdf_document:
includes:
in_header: header.tex

Where the header.tex should include the following code:
\usepackage{titling}
\pretitle{%
\begin{center}
\LARGE
\includegraphics[width=4cm,height=6cm]{logo.png}\\[\bigskipamount]
}
\posttitle{\end{center}}
and replace logo.png with the image you would like to use and make sure the file is in the root directory of your Rmd file. You can change image width and height to your needs. For more information on available options go to titling
For a beamer presentation you can do it like this:
title: "Title"
subtitle: "Subtitle"
author: "author"
date: "date"
header-includes:
- \titlegraphic{\centering \includegraphics[width=12cm]{titlepic.png}}
output:
beamer_presentation:
latex_engine: xelatex
theme: "metropolis"
highlight: "espresso"
classoption: "aspectratio=169"
The titlegraphic will be placed below your title text
For beamer presentation if you want an image at the bottom you can kind of cheat and add the image where the date line should be. Then if you want to insert date you can add institution (which is before date). the ![] should be tabbed (4 spaces from the far left of the page)
date: |
{width=3in}
