I'm wondering how to change font and color specifically for figure captions in Rmarkdown for a PDF output. I know how to do this for word output (creating a separate document), but often figures are submitted to journals as PDFs.

Note that this is not whether you can change the color of text in a PDF which is answered here: Changing the font size of figure captions in RMarkdown pdf output. If I try this within the fig.cap = "fig text here.\\label{...}" I get the following error:

I am currently preparing html slides for an R modelling workshop, for which I use the awesome xaringan package for R. It is based on remark.js. Compared to ioslides and slidy, it does much better suit my expectations. I am absolutely excited! One feature that I missed, are scrollable "long slides". Here I leave of course the "slides" paradigm towards a mix between slides and ordinary web pages, but I find this didactically attractive to explain complex content and code. This style worked well with slidy, and I found also some hints how to enable scrollable code in xaringan.

Here I use the following CSS (found in a related post at SO):

The objective of my code is to scrape the information in the Characteristics tab of the following url, preferably as a data frame

I just noticed that read_csv() somehow uses random numbers which is unexpected (at least to me). The corresponding base R function read.csv() does not do that. So, what does read_csv() use the random numbers for? I looked into the documentation but could not find a clear answer to that. Are the random numbers related to the guess_max argument?

I often create fairly large dashboards with R Markdown. Every time I create a new output (e.g., a new chunk containing an additional table or chart), I want to check for any display issues. My current workflow for doing this is slow for two reasons:

1. I want to test in the browser, but there doesn't seem to be an option to knit a document directly to the browser, so I have to knit to the default window and then click "Open in Browser" (see also here When knitting RMarkdown to HTML with RStudio, is it possible to view directly in browser, instead than previewing in a window?);
2. I do not know of a way to only knit a subset of chunks. For example, is there a way to knit in "test" mode, whereby only certain marked chunks are knitted?

Thanks for any advice.

If I use \FloatBarrier to maintain the desired order of the document, I get the following error and can't knit the PDF (specifically happens with PDF). It worked probably six months ago.

I discovered this RMarkdown document in this video and I am wondering how the creator of this Markdown document was able to shift the pear images to the left while maintaining the text on the left side of the document. From my understanding this requires understanding some HTML to move these objects. I know a little know understand this but not enough to implement this. Would anyone have any ideas on how to do something like this?

The main reason I want to do something like this is because I want to create a dashboard style RMarkdown document (not using Flexdashboard or Shiny, strictly Markdown)

Desired Output of a document: In short, how did the author get the image of this peach on the left side of this document?

I want to create a footer within the float for a figure created with ggplot2 in an rmarkdown document that is generating a .pdf file via LaTeX.

My question: Is there a way within rmarkdown/knitr to add more LaTeX commands within the figure environment?

Specifically, I'd like to find a way to insert custom LaTeX using either the floatrow or caption* macro as described in https://tex.stackexchange.com/questions/56529/note-below-figure within the figure environment.

When I looked at the chunk options (https://yihui.org/knitr/options/#plots), something like out.extra seems close to what I want, but that is used as an extra option to \includegraphics while I want access to put extra LaTeX within the figure environment, outside of any other LaTeX command.

I need to include the following code in a .tex file that is generated from a custom template via RMarkdown, in order to get rid of an error. However, if I try it as below in the YAML heading:
