If it doesn't work well or if you want to handle the LaTeX to R Markdown conversion manually (given the limited elements), you can start with small steps such as using:

# and ## (or ## and ### respectively, adjusting the number of # accordingly for the desired header size) in place of \section{} and \subsection{}
- A
- B
instead of:
\begin{itemize}
\item A
\item B
\end{itemize}
| A | B |
|---|---|
| C | D |
| E | F |
instead of:
\begin{tabular}{|c|c|}
\hline
A & B \\
\hline
C & D \\
E & F \\
\hline
\end{tabular}
[@citationID] instead of \cite{citationID}
**word** instead of \textbf{word}, *word* instead of \textit{word}, etc.
