如何在标题页的标题下方添加图像？

Question

我正在编写数据分析报告。在我的封面上，我想在标题下方和作者上方的空白处插入图片。

我的代码如下所示。

它生成以下输出：

由于我已经成功添加了徽标，因此我尝试将同一行的副本放置到代码中的不同位置，但是我遇到一个错误，提示它无法编译（当我尝试将其编织为pdf时）或图像不显示。

要使其尽可能简单，只需使用subtitle：

output:
  pdf_document: 
    keep_tex: true
title: "Test"
subtitle: "\\includegraphics{unnamed.png}\\vspace{4in}"
