LaTeX wrapfigure in RMarkdown

I am trying to use rmarkdown to generate a PDF via LaTeX. I am trying to embed an image into PDF using LaTeX commands with RMarkdown document. I am using the LaTeX command wrapfigure

that inserts the shape correctly and then forces the text following the current section into a narrower column, as shown here .

My PDF looks like this:

text text text [image]

text text text

text text text

I want to:

text text text [image]

text text text text

text text text text

The solution to this problem is to use the full LaTeX document, but I need to use RMarkdown for my class, so the solution won't work for me. How do I get the full string formatting I want using RMarkdown?

Sample code:

---
title: "Really Awesome Title"
author: "Some Guy"
date: "June 30, 2017"
output:
  pdf_document: default
urlcolor: blue
header-includes:
   - \usepackage{wrapfig}
---

\begin{wrapfigure}{R}{.25\textwidth}
  \begin{center}
    \includegraphics[width=.2\textwidth]{Dave_roberts.png}
  \end{center}
  \caption{Dave Roberts}
\end{wrapfigure}

UPDATE: A friend suggested that I end the LaTeX section of code with {R}. This caused the margin error to end but added the text "{R}" to my PDF.

The code now looks like this:

\begin{wrapfigure}{R}{.25\textwidth}
  \begin{center}
    \includegraphics[width=.2\textwidth]{Dave_roberts.png}
  \end{center}
  \caption{Dave Roberts}
\end{wrapfigure}{R}

      

        
        
        
      

    

So this is the problem with the LaTeX call ending. Does anyone know how to end the LaTeX call but not add text to the PDF?
