I want to insert a picture at the beginning of text using a code block, not markdown. I am using the Tufte handout template output: rmarkdown::tufte_handout and when I insert it straight after the YAML header but before TOC like this:
\centering
\raggedright
\tableofcontents
\clearpage
the image then spans the main body. I know that with chunks there is an option to have the chunk to span the whole page placing fig.fullwidth = TRUE in the chunk header, but I am a bit stuck with this as I am not generating any graph from data and I do not know how to simpy place an image from within a chunk.
Another matter was that when I set toc: true in the YAML header, the image would only come after the inserted toc - that is why I am inserting toc with the latex command.
Thank you for your suggestions.
When a figure is not generated from R code, you may use knitr::include_graphics() to insert it to the document, e.g.
```{r echo=FALSE, out.width='100%'}
knitr::include_graphics('./cropped-banner_efpt.jpg')
```

Text in the code section of a Tufte formatted, Rmarkdown document does not seem to wrap. I have tried several options and suggestions, but nothing works. I am guessing that all of the other suggestions I could find on StackOverflow did not work, because of the "tufte" format. I am using knitr to construct HTML or PDF documents. Here is the minimal example:
---
title: "Width Minimal Example"
output:
tufte::tufte_handout: default
tufte::tufte_html: default
---
```{r setup, include=FALSE}
library(tufte)
library(formatR)
# invalidate cache when the tufte version changes
knitr::opts_chunk$set(tidy = TRUE, cache.extra = packageVersion('tufte'))
options(htmltools.dir.version = FALSE)
```
```{r, tidy='styler', tidy.opts=list(width.cutoff=50)}
filename <- "/Test/test/test/test/test/test/test/test/test/test/test/test.data"
```
When I use knitr to produce HTML or PDF (handout), the "filename" variable runs out of the textbox allotted for code. I've looked through the "tufte.css" file and nothing there seems to describe the width of text in code boxes.
Ideally, the text in the code box would not only wrap, but indent a bit so that the person reading the code would easily be able to see which lines were new lines and which lines were wrapped lines. Thanks!
I think the question is quite self-explanatory but for avoidance of doubt I'll explain with more detail below:
I have an R Markdown document that works well if converted to HTML or uploaded to GitHub. When converting to PDF (using Latex), the results are not so pretty. I find that the biggest problem in a Latex PDF document are line breaks. I can fix the line breaks issue on the PDF document by adding "\ " characters, but that throws my HTML document out of whack too.
Is there a way to manually add line breaks (or "space before/after paragraphs") for the PDF output only?
Thank you!
You can redefine the relevant spacings in the YAML header. \parskip controls the paragraph spacing. Code blocks are shaded using a snugshade environment from the framed package. We can also redefine the shaded environment for code blocks to have some vertical space at the start. Here's a reproducible example. Note: I also added the keep_tex parameter so you can see exactly what the generated tex file looks like, in case this is useful:
title: "test"
author: "A.N. Other"
header-includes:
- \setlength{\parskip}{\baselineskip}
- \renewenvironment{Shaded}{\vspace{\parskip}\begin{snugshade}}{\end{snugshade}}
output:
pdf_document:
keep_tex: true

```{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.
Once you output to HTML, you can just print the HTML webpage as PDF. that might be an easy way keep the original format
I am trying to add a cover page which is already created in a PDF.
```{r echo=FALSE,out.width='8.27in',out.height='11.69in'}
knitr::include_graphics('CoverPage.pdf')
```
I want to change the margins of the first page only. Can you please help me with this?
The following was tried but it changes the margin of the whole document:
geometry: "left=3cm,right=3cm,top=2cm,bottom=2cm"
If you are fine with some bare LaTeX in your RMD file, then this can be easily achieved using the geometry package. Just define a newgeometry before the cover is included and restoregeometry afterwards (reads almost like English …).
---
output:
pdf_document
---
```{r, echo = FALSE, results = "asis"}
cat("\\newgeometry{left=3cm,right=3cm,top=2cm,bottom=2cm}")
knitr::include_graphics("CoverPage.pdf")
cat("\\restoregeometry")
```
\clearpage
Note the position of the page number. Restoring the margins was successful!
It is important to use the chunk option results="asis" and cat() to print raw LaTeX and to escape the backslashes with an additional backslash.
I am trying to add section slides to a beamer presentation written in rmarkdown using the latex command \section{}. However, it gets inserted between a \begin{frame} & \end{frame} automatically during the conversion, which causes the compilation to fail. Is there any way to stop this happening so that the section slide can be added without having to manually edit the tex file?
Here is my rmarkdown code:
---
title: "Beamer presentation"
output: beamer_presentation
---
\section{Section one}
which gets converted to:
\title{Beamer presentation}
\begin{document}
\frame{\titlepage}
\begin{frame}
\section{Section one}
\end{frame}
\end{document}
Slides and section slides are both defined by markdown headings, a series of # character at the beggining of a line, the number of # indicating the hierarchical level of the title.
By default [the level that defines frames] is the highest header level in the
hierarchy that is followed immediately by content, and not another
header, somewhere in the document.
All title of higher level than this one will become section titles.
From the rmarkdown documentation ; See also the pandoc documentation on slideshows.
For instance :
# Section title
## Frame title
Frame content
### Subtitle inside a frame
I am trying to insert logo into beamer presenation using Rmarkdown, and it looks like size controls in \logo{\includegraphics[height=1cm,width=3cm]{logo.png}} do not work, no matter what values I put there, image is always of the same size. Any suggestions besides modifying image manually?
---
title: "Presentation"
author: "Author"
output:
beamer_presentation:
includes:
in_header: mystyle.tex

## 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)
```
This is mystyle.tex
\logo{\includegraphics[height=1cm,width=3cm]{logo.png}}
\usetheme{Madrid}
\usefonttheme{serif}
\institute{Institute}
\setbeamertemplate{navigation symbols}{}
UPDATE: Quick work around - simply modifying image will not work - image is ugly and pixelated. Simply converting to pdf also didn't work well, so I used following R code to create pdf and use it in \logo{\includegraphics{logo.pdf}}
library(png)
library(grid)
img <- readPNG('logo.png')
img <- rasterGrob(img, interpolate=TRUE)
pdf(file = 'logo.pdf', width = 1, height = 0.25)
grid.newpage()
grid.raster(img)
dev.off()
I found solution; in beamer manual there is another way of using logo function and it works fine.
\pgfdeclareimage[height=0.2787cm, width=2.5cm]{logo}{logo.png}
\logo{\pgfuseimage{logo}}
I found this beamer tutorial quite useful. Just add the following to the file mystyle.tex passed to the YAML option in_header (as shown in the question):
\usepackage{tikz}
\titlegraphic {
\begin{tikzpicture}[overlay,remember picture]
\node[left=0.2cm] at (current page.30){
\includegraphics[width=3cm]{Beamer-Logo}
};
\end{tikzpicture}
}
and then you can play around with the node parameters to adjust the placement of your logo (Beamer-Logo).
