One way to add color to a README is by utilising a service that provides placeholder images. For example this Markdown can be used: –  `#f03c15` –  `#c5f015` –  `#1589F0` To create a list of any colors you like: #f03c15 #c5f015 #1589F0
This code is rather long. I apologize. It consists of two stored procedures. You may be satisfied running just the first one. The second uses the output from the first (the data the first left in tables). You may also wish to combine the code into one. But I kept them separate. The second stored … Read more
The question is old, but still receives a lot of attention. As the existing answers are outdated, here a more up-to-date solution: Resizing local images As of knitr 1.12, there is the function include_graphics. From ?include_graphics (emphasis mine): The major advantage of using this function is that it is portable in the sense that it … Read more

It doesn’t really do document layout. For example, there’s no real way to align an image to the right or left. As to … Read more
I present an alternative solution. Instead of inserting [H] symbols into a latex document in a post-hoc manner, I suggest redefining the figure environment to ignore any position arguments and use [H]. To do this, create a .tex file in the same directory as the .Rmd file which redefines the figure environment, and update the … Read more

To insert an anchor point of that name use HTML: <a name=”pookie”></a> Markdown doesn’t seem to mind where you put the anchor point. A useful place to put it is in a header. For example: ### <a … Read more
As far as the Markdown syntax is concerned, if you want to get that detailed, you’ll just have to use HTML. <a href=”http://example.com/” target=”_blank”>Hello, world!</a> Most Markdown engines I’ve seen allow plain old HTML, just for situations like this where a generic text markup system just won’t cut it. (The StackOverflow engine, for example.) They … Read more
You could just use some HTML in your Markdown: <img src=”https://stackoverflow.com/questions/14675913/drawing.jpg” alt=”drawing” width=”200″/> Or via style attribute (not supported by GitHub) <img src=”https://stackoverflow.com/questions/14675913/drawing.jpg” alt=”drawing” style=”width:200px;”/> Or you could use a custom CSS file as described in this answer on Markdown and image alignment  CSS in another file: img[alt=drawing] { width: 200px; }
I believe that all the previously proposed solutions (apart from those that require specific implementations) result in the comments being included in the output HTML, even if they are not displayed. If you want a comment that is strictly for yourself (readers of the converted document should not be able to see it, even with … Read more
