How to separate Title Page and Table of Content Page from knitr rmarkdown PDF?

Question

Anyone have any idea how to separate Title Page and Table of Content page? From this code:

---
title: "Title Page"
output: 
  pdf_document:
      toc: true
      number_sections: true
---

The few line of code above creates the Title and Table of Content, but there is no separation between the Title Cover Page and Table of Content.

I have found an alternative by adding latex symbols \newpage and \tableofcontents:

---
title: "Title Page"
output: 
    pdf_document
---

\centering
\raggedright
\newpage
\tableofcontents

# header 1
```{r}
summary(cars)
```

## header 2
```{r, echo=FALSE}
plot(cars)
```

## header 3
lore ipsum 

# header 4
lore ipsum

Is there a way without having to use latex \newpage and \tableofcontents and use rmarkdown somewhere in the following block:

---
title: "Title Page"
output: 
    pdf_document:
        toc: true
---

Answer 1

I used a trifecta of latex files in the options under includes:

---
title: "Title Page"
output: 
  pdf_document:
  toc: true
    number_sections: true
  includes:
    in_header: latex/header.tex
    before_body: latex/before_body.tex
    after_body: latex/after_body.tex
---

The before_body file contain all of the options you would want AFTER the \begin{document} and the title options, but BEFORE you start writing the body of your document. In that file, simply place a \newline, like so:

\newpage

That's it! Nothing else in the before_body.tex file. That should work.

Now, if only I could vertically center the title page...
