Remove colon in figure caption using pandoc and bookdown in R Markdown

Asked 2022-Mar-29 at 16:42

I am changing the font of a figure caption in my R Markdown and am using bookdown and pandoc to do so. My question is closely related to: How to change the figure caption format in bookdown?. I was able to get correct figure numbering and was able to alter the format of the "Figure 1" portion of the caption. However, I cannot figure out how to remove the colon in the output (i.e., "Figure 1:. ").

Looks like there was a change in rmarkdown which adds a colon by default. Also the reason why the answer in the linked post does not work anymore. For more on this and a solution see https://community.rstudio.com/t/how-to-change-the-figure-table-caption-style-in-bookdown/110397.

Besides the solution offered there you could achieve your desired result by replacing the colon by a dot. Adapting the lua filter provided by https://stackoverflow.com/a/59301855/12993861 this could done like so:

We can use htmlwidgets::onRender to pass custom JS code to the leaflet htmlwidget.

With the help of the eachLayer method we can add an on-click function to each polygon layer:

How to extract all code from an RMarkdown (.Rmd) file?

Asked 2022-Feb-19 at 12:21

How can I extract all the code (chunks) from an RMarkdown (.Rmd) file and dump them into a plain R script?

Basically I wanted to do the complementary operation described in this question, which uses chunk options to pull out just the text (i.e. non-code) portion of the Rmd.

So concretely I would want to go from an Rmd file like the following

Yes, this is possible. You can use local data or data stored somewhere--like Google Sheets.

Step 1) Add runtime: shiny to your YAML. This does not make this "shiny", but does make it dynamic.

QUESTION

Accessing the original file name of R markdown parameters file

Asked 2022-Jan-20 at 23:04

I want to provide the user a convenient way to define the input file. For this I am using the parameters functionality in markdown. If I "knit with parameters" I get asked for the input file.

Is there any chance to retrieve the file name? Because I am creating during the markdown some different files and I would use the filename of the input file as a prefix. So far, the file gets uploaded in a temp directory and there, the original file name is lost.

How can I get the file name and location via drop down menu into my markdown document? I don't want the user to write the path and filename manually.

You could have users select a file in the rendered document by embedding a Shiny application. The caveat is that all expressions involving dependencies of the user's selection have to be wrapped inside of reactive(). That is obviously not optimal if you are trying to teach R, but in case it helps or inspires a better answer, here is an example:

Efficient, but not exact

For the example setup, I would recommend splitting up the operations to easily fit them side-by-side using pandoc syntax for multiple columns. In this way, we can just call the specifics we want.

QUESTION

IDE with LaTeX and R support: Inline output in .Rmd notebooks and weaving LaTeX document with R code

Asked 2022-Jan-03 at 11:40

I'm trying to improve my workflow when working with R and generating documentation. I've been going between TeXStudio, JupyterLab and RStudio for a while, and I'm trying to improve my workflow. TeXStudio has limited R support, and RStudio limited support for LaTeX.

VS Code has support for multiple languages, including R and LaTeX. The fact that it can run both Jupyter notebooks, R notebooks, and LaTeX, and has plugins for other languages as well, makes it seem desirable. However, I am unable to find documentation on how to configure it to work with R and LaTeX code in the same file. In addition, I am unable to configure R notebooks to allow inline code execution output.

However, I am unable to (a) set up code execution output under the code for .Rmd notebooks, and (b) I can't figure out how to weave .Rnw (R/LaTeX) documents with Sweave/knitr.

I'm trying to find an IDE that would include features like:

Markdown, code and code execution output in the same document
Auto R and LaTeX code completion
Automatic display of R function documentation
Spell check
Simple R console access
Compile .Rnw
Syntax highlighting for both R code and LaTeX code

I am, primarily, requesting ways to configure VS Code, or, secondly, way to configure another IDE that can meet my requirements. A tutorial on this would be much appreciated.

ANSWER

Answered 2022-Jan-03 at 11:40

After a bit of digging around, I found that VS Code does nearly all the things I need.

Auto R and LaTeX code completion, Display of R function documentation in a tab in VS Code, Simple R console access, and Syntax highlighting for both R code and LaTeX code:

The R and LaTeX Workshop extensions, will provide highlighting and autocompletion of code in both languages. By installing R, you can easily open a session in a terminal window in VS Code, and from there open documentation inside VS Code.

Spell check

Code Spell Checker offers spell check for multiple languages. Install the extension and any desired dictionaries, and set the langauges you want to be included in the extension settings.

Compile .Rnw files

Turns out LaTeX Workshop can actually do this by default.

Markdown, code and code execution output in the same document

This is the only thing VS Code doesn't do as far as I can tell. It can compile .Rmd files, however, but the output can only be seen in the compiled PDF. I consider this less important, since I can use Jupyter notebooks instead.

How can I filter pre-aggregated data in Rmarkdown without Shiny?

Original Question (See update with partial solution below.)

I have an RMarkdown document which summarizes how many records (rows) have various attributes by group. I would like to be able to manipulate which records are included in the table by filtering before the summarizing. I've created a minimal but similar mockup below.

What I would like is an interactive checkbox that would effectively "comment or uncomment" out the line
