Add beamer frame options in knitr/rmarkdown

rmarkdown uses pandoc to convert a Rmd file to a pdf via beamer/latex. pandoc uses templates to control how the conversion goes.

One way to deal with your problem is to :

1. Download the default beamer template rmarkdown uses and open it.

2. Change line 137 from this :

   \frame{\titlepage}
   

   To this :

   \frame[plain]{\titlepage} 
   

3. Add the path to your modified template in your Rmd file :

   ---
   output:
     beamer_presentation:
       includes:
         in_header: header.tex
       template:/path/to/new/template.tex
   ---
   

Note that you need to specify the whole path, or store the template where pandoc can find it (~/.pandoc/templates on a linux machine)

Add {.plain} after the title as in:

----

# I'm the title {.plain}
