I would like to include external markdown file covering inline code as well. Once I hit the Knit on RStudio, it does show only code text rather than the actual value of sys.time. If I place the content of about.md into the main.Rmd, there is no issue. The point should be related with includeMarkdown but it does not take any parameter except than path. Any suggestions ?
Thanks in advance
main.Rmd
---
title: "test"
author: "test"
output:
flexdashboard::flex_dashboard:
orientation: rows
social: menu
vertical_layout: fill
---
```{r}
htmltools::includeMarkdown('about.md')
```
about.md
Today is `r format(Sys.time(), "%d %B %A %Y")`
Current Output
Today is r format(Sys.time(), "%d %B %A %Y")
htmltools::includeMarkdown() only includes plain Markdown, not R Markdown. Your about.md is actually R Markdown---it contains R code to be evaluated.
To include an R Markdown document in another one, you can use the chunk option child:
```{r, child='about.Rmd'}
```
I suggest you rename about.md to about.Rmd.

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)
```

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>.
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
I was told to write a report in R Markdown with the following template:
---
title: "Data Dictionary"
output: github_document
date: "Last Updated: `r format(Sys.time(), '%d, %B, %Y at %H:%M')`"
---
I want to use readthedown theme from rmdformats package, however I could not find a tutorial on how to do so properly. My question is, is it possible to use a theme with this template? Any help would be appreciated!
Assuming you already have installed the package, remotes::install_github("juba/rmdformats"), just pass rmdformats::readthedown to the output YAML:
---
title: "Untitled"
date: "Last Updated: `r format(Sys.time(), '%d, %B, %Y at %H:%M')`"
output: rmdformats::readthedown
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
## 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.
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.

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 have an R markdown presentation that I would like to create different versions of. One of the things I was hoping to accomplish by doing this is changing the headers of a slide in the presentation based on some value that I've defined.
For example:
mytitle <- 'R Markdown Presentation'
I would like the value that is stored in mytitle to be the value that is used for the header. So the header would say "R Markdown Presentation". I have attempted the following solutions, but none have worked:
## title
## `title`
## eval(title)
```{r}
pres_title <- 'R Markdown Presentation'
pres_author <- 'Me'
pres_date <- Sys.Date()
```
---
title: `r pres_title`
author: `r pres_author`
date: `r pres_date`
output: html_document
---
Four years later and I was also looking for a clean way to do it, in a Notebook with R Studio. The original question was exactly what took me here. The answers helped, but I want to stress out that we can also do it almost as requested by Harrison Jones, in his example.
Define vars first:
myTitle1 <- 'R Markdown Presentation'
mySecondTitle2 <- 'Cool things regarding R notebooks'
And then apply them in markdown headers, along the text, as you wish, with inline R code:
# `r myTitle1`
## `r mySecondTitle2`
This is a R notebook example, with two headers and a paragraph.
You can also generate the entire header line, including markdown, by inline R code, like in the following example:
`r paste("#", myTitle1, sep=" ")`
`r paste("##", mySecondTitle2, sep=" ")`
This is a R notebook example, with two headers, a paragraph
and a beautiful table printed using knitr:
`r knitr::kable(cars)`
R Notebooks are a easy and powerfull.
When using R Studio, I prefer something like:
---
title: !r "An Example R Markdown Beamer Presentation"
author: !r "Me"
date: !r Sys.Date()
output: beamer_presentation
---
Inserting code before yaml header can interfere with output format. In this example I used beamer_presentation output so you can test it yourself.
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

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

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}
