Create HTML slides with knitr, Rmarkdown and pandoc

Question

I am trying to create a HTML slides with knitr, Rmarkdown and pandoc. I got a reference from http://rprogramming.net/create-a-slideshow-powerpoint-with-r-knitr-pandoc-and-slidy/ .

But I meet a problem at the step5. After executing

knit("test4.Rmd")
system("pandoc -s -t slidy test4.md -o test4.html")

I got a message

pandoc.exe: Could not parse YAML header: found character that cannot start any token "source" (line 13, column 1)

Please help me to solve this problem. Thanks in advance!

Answer 1

You can check your line 13 in your md file. and change --- into ----- or more. This is how I solved my problem.

Obviously it has something to do with YAML header. I just got inspiration from another stackoverflow answer , so I figure maybe change the --- with ---- (just add more - )can prevent the pandoc from treating it as a YAML block.
