解决方案

通过markdown插入其他框架，因为即使没有内容实际打印到该框架，它也会自动启动不必要的框架.通过将 \ tocframe 放在 \ titleframe 之后，可以避免标题和toc框架之间的空白.

对于黑框，您可以定义一个新的宏，例如

  \ newcommand {\ blackframe} {{\ setbeamercolor {background canvas} {bg = black} \ begin {frame} [plain] \ end {frame}}}

I use a custom LaTex beamer theme in an rmarkdown::beamer_presentation.As per these SO answers (LaTex theme, colon, theme path), I used several modifications of the YAML header and beamerthemeTHEMENAME.sty.These LaTex hacks are necessary to apply the LaTex Beamer theme smoothly in the rmarkdown::beamer_presentation.

However, currently, a blank slide is inserted by LaTex before and after the table of contents (ToC) slide (see fig 1 below).

How can I get rid of these slides?
Instead, I would ideally have a completely black slide before the ToC and at other instances during the presentation (i.e., to briefly interrupt and "switch off" the presentation in between)

Note: if I use the option toc: true to generate the ToC (instead of using the \tocframedefined in beamerouterthemeTHEMENAME.sty), markdown messes up the vertical alignment of the ToC and it comes without any headline (see fig 2 below).

Fig 1: using Tocframe from LaTex Template to generate ToC (`toc:false` in YAML header)

Fig 2: using `toc:true` in YAML header to generate ToC

解决方案

The additional frames are inserted by markdown because it will automatically start unnecessary frames even if none of the content is actually printed to the frame. You can avoid the empty frame between the title and your toc frame by placing the \tocframe after your \titleframe.

for black frames, you can define a new macro, e.g.

\newcommand{\blackframe}{{\setbeamercolor{background canvas}{bg=black}\begin{frame}[plain]\end{frame}}}
