In the LaTeX template <R-Library>/rmarkdown/rmd/latex/default-1.17.0.2.tex
we see
\begin{document}
$if(title)$
\maketitle
$endif$
$if(abstract)$
\begin{abstract}
$abstract$
\end{abstract}
$endif$
$for(include-before)$
$include-before$
This means that a titlepage is created using \maketitle
if a title
is defined in the YAML headers. Similar for the abstract
. If you remove both these tags from your YAML headers, then the content from the file body.tex
will be the first to be processed and you are free to customize your titlepage there.
