r-markdown

In rmarkdown PDF and HTML I want two bibliographies —one for papers/books, and one for software I have used in my research. I found this related issue but it doesn't answer my question since it's concerning the combination of two *.bib files into one bibliography. I'm used to place my bibliography with <div id="refs"></div> as explained here . Possibly a second one can be placed similarly with <div id="refs_2"></div> , but I couldn't figure out how to do it since this "refs" seems not to be defined anywhere. I usually define the software in the YAML header like this nocite: | @xie_knitr:_2018,

Currently there seem to be two ways to do presentations in R: RStudio presentations , with .Rpres extension rmarkdown , with .Rmd extension To me, it looks like the latter is slightly more powerful. The input format is very similar, yet not identical. I'm thinking about converting an RStudio presentation to rmarkdown. What's the best way to do this? How about the conversion back? On that note, I'd really like to see an "in-pane" preview for rmarkdown presentations in RStudio, just like for RStudio presentations. I wonder why this isn't implemented -- the preview forcibly shows up in a modal

The results = 'asis' chunk option within Rmarkdown allows one to easily dynamically create text including headers. However, I wish to dynamically create a header with the asis option, but then in the same code chunk insert some graphics. The most related answer I could find for this is here: Programmatically insert text, headers and lists with R markdown , but the answer to this question does not allow both dynamic headers and plots within those dynamic headers. Here is a simple reproducible example follows demonstrating what I can and cannot achieve with results = 'asis' The code directly

I am trying to create a multi-line equation in RMarkdown. I have tried the following code, extracted from http://www.rstudio.com/ide/docs/authoring/using_markdown_equations , $$ \begin{aligned} \dot{x} & = \sigma(y-x) \\ \dot{y} & = \rho x- y - xz \end{aligned} $$ however the knitred HTML document gives a single-line equation: This code produced 2 HTML lines, as desired, when cut and paste into RStudio in Windows 7 with knitr. If the second slash at the end of the 3rd line was removed, it produced the result shown in example. 来源： https://stackoverflow.com/questions/21126776/multi-line-equation

Is it possible to embed a YouTube video in a R Markdown? So far what I have is <a href="http://www.youtube.com/watch?feature=player_embedded&v=Q8rakpF7duU " target="_blank"><img src="http://img.youtube.com/vi/Q8rakpF7duU/0.jpg" alt="IMAGE ALT TEXT HERE" width="240" height="180" border="10" /></a> but it only adds an image. Clicking on this image takes me to my browser where the video starts playing. Is there a way that allows me to play the video in the markdown document itself?

I am using RMarkdown to create an ioslide presentation with shiny. Some of my slides do not actually fit on one page and are truncated. Since this is a HTML output, I would like to add a scroll bar to make my long slides scrollable. I have been googling a lot and found a partial solution to make R code chunks scrollable . However I want to make my slides scrollable regardless of the content. This is a toy Rmd example giving slides not fitting on one page: --- title: "Untitled" date: "30 October 2018" output: ioslides_presentation runtime: shiny --- ```{r setup, include=FALSE} knitr::opts_chunk

Using what is currently the development version of RStudio (0.98.758), I'm loving that I can author an ioslides presentation in rmarkdown . The rmarkdown docs for this format give a description of how to do a two-column slide, and it comes with the warning that: Note that content will flow across the columns so if you want to have an image on one side and text on the other you should make sure that the image has sufficient height to force the text to the other side of the slide. But I can't seem to possibly make an image big enough! Text still gets pushed off the bottom of the first column. In
