rmarkdown | Dynamic Documents for R

I have an Rmarkdown with a simple scatter plot (a map for instance), and I would like users to be able to provide some arbitrary x and y coordinates via an input and have those plotted on the graph (in red in the example below). The problem is, I don't have a shiny server so I cannot rely on that option. Is there a implement this, for instance, via javascript or something?

This is what I have:

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

Is there a way to have the data associated with and html output file generated via Rmarkdown be loaded dynamically (e.g., via javascript or ajax) when opening the html output?

For instance, I have this simple Rmarkdown file which produces a plot (in svg) and a table:

In a R Notebook there is a function that makes many plots and print summary statistics in the console. I would like to get the plot and the console output (i.e. summary statistics) side by side on the HTML output.

Here is a very simple example:

I would like to use a live timestamp in my rmarkdown file. To do so, I need to include the jquery and moment.js libraries. However, the jquery library conflicts with the datatable R library. I tried many solutions I saw online, without success.

This is my header (header.html) with the jquery, moment.js and livestamp.js libraries:

My website https://friendly.github.io/HistDataVis/ wants to use the seemingly light weight and useful discussion feature offered by the https://github.com/utterance app.

I believe I have installed it correctly in my repo, https://github.com/friendly/HistDataVis, but it does not appear on the site when built.

I'm stumped on how to determine what the problem is, or how to correct it. Can anyone help?

For reference, here is my setup:

• The website is built in R Studio, using distill in rmarkdown.

• I created utterances.html with the standard JS code recommended.

I would like to have a point displayed (like in this tutorial) in my rmarkdown document after knitting.

Reproducible example:

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

I am making a book via bookdown. I know it is possible to omit headings from the Table of Contents by adding the attributes {.unlisted .unnumbered}, as shown in Section 4.18 of the R Markdown Cookbook. However, how can I add arbitrary content to the Table of Contents? If I only needed to add this for the PDF output, I could use (e.g.) the LaTeX command \addcontentsline, but I need this to show in the HTML contents sidebar as well.

For example, if you set up a new default bookdown project from RStudio, it includes the file 01-intro.Rmd. The first few lines are
