Company logo in PDF output only on the first page

问题

I was wondering if there is a way to include the company logo to a PDF document created by R Markdown only on the first page of the document. I have searched for an answer and the closest I could find is this. There are multiple solutions presented in the answers, however, neither of them works for me because they either:

include the logo at every page of the document (not just first); or
include the chapter title in the header (and a horizontal line below it) along with the logo.

I am looking for a way to include just the plain logo, with no chapter titles only on the first page of a PDF R Markdown document and I've ran out of all the resources I could find online. Is there someone who could aid me?

Before anyone asks: yes, it strictly has to be a PDF document, not HTML.

回答1:

The \includegraphics code line is insert after the R SETUP chunk in markdown. Here is an example of where I put the line \includegraphics :

---
geometry: "margin=1.5cm"
classoption: landscape
output:
  pdf_document: # Export to pdf
    number_sections: yes 
includes:
          in_header: ltx.sty
---



```{r SETUP, include=FALSE, message=FALSE, warning=FALSE}

knitr::opts_chunk$set(echo = FALSE,  
                  warning = FALSE,  
                  message = FALSE,  
                  results = "asis")

library(knitr) 
library(kableExtra) 
library(some_packages)

options(scipen = 999,
    digits = 2,
    width = 110)

```

\definecolor{astral}{RGB}{87,146,204}
\allsectionsfont{\color{astral}}
\setcounter{tocdepth}{5}


<!-- Title page -->
\includegraphics[width=7cm]{logo.jpg}

\begin{center}\begin{Large}
Project 1
\end{Large}\end{center}

\vfill


# Some R chunk
```{r results='asis'}
# Table, code, graphics.
```

So the line is insert between the R SETUP chunk and the next R chunk.
