Quick Summary
How do I place HTML files in place within an R Markdown file?
Details
I have created some nice animated choropleth maps via choroplethr.
As the link demonstrates, the animated choropleths function via creating a set of PNG images, which are then rolled into an HTML file that cycles through the images, to show the animation. Works great, looks great.
But now I want to embed / incorporate these pages within the .Rmd file, so that I have a holistic report including these animated choropleths, along with other work.
It seems to me there should be an easy way to do an equivalent to
Links:

or
Images:
The images path is precisely what I want: a reference that is "blown up" to put the information in place, instead of just as a link. How can I do this with a full HTML file instead of just an image? Is there any way?
Explanation via Example
Let's say my choropleth HTML file lives in my local path at './animations/demographics.html', and I have an R Markdown file like:
---
title: 'Looking at the demographics issue'
author: "Mike"
date: "April 9th, 2016"
output:
html_document:
number_sections: no
toc: yes
toc_depth: 2
fontsize: 12pt

# Introduction
Here is some interesting stuff that I want to talk about. But first, let's review those earlier demographic maps we'd seen.

where I have assumed / pretended that !! is the antecedent that will do precisely what I want: allow me to embed that HTML file in-line with the rest of the report.
Updates
Two updates. Most recently, I still could not get things to work, so I pushed it all up to a GitHub repository, in case anyone is willing to help me sort out the problem. Further details can be found at that repo's Readme file.
It seems that being able to embed HTML into an R Markdown file would be incredibly useful, so I keep trying to sort it out.
(Older comments)
As per some of the helpful suggestions, I tried and failed the following in the R Markdown file:
Shiny method:
```{r showChoro1}
shiny::includeHTML("./animations/demographics.html")
```
(I also added runtime:Shiny up in the YAML portion.)
htmltools method:
```{r showChoro1}
htmltools::includeHTML("./animations/demographics.html")
```
(In this case, I made no changes to the YAML.)
In the former case (Shiny), it did not work at all. In fact, including the HTML seemed to muck up the functionality of the document altogether, such that the runtime seemed perpetually not-fully-functional. (In short, while it appeared to load everything, the "loading" spindel never went away.)
In the latter case, nothing else got messed up, but it was a broken image. Strangely, there was a "choropleth player" ribbon at the top of the document which would work, it's just that none of the images would pop up.
For my own sanity, I also provided simple links, which worked fine.
[This link](./animations/demographics.html) worked without a problem, except that it is not embedded, as I would prefer.
So it is clearly a challenge with the embedding.
