r - Adding a footnote / thanks to Rmarkdown title slide -

i have include note in title slide declaring source of funding. able in lyx / latex through:

\author{michael chirico\thanks{these people gave me money}, other authors} 

i have not been able reproduce in rmarkdown. site mentions using [^] anchoring mark footnotes, , works fine in other slides, couldn't work in title:

--- title: "title" author: "michael chirico[^thanks], other authors" date: "february 10, 2016" output: beamer_presentation  [^thanks]: these people gave me money --- 

the .pdf compiles there no title slide. think relevant part of compilation log:

pandoc: not parse yaml header: unexpectedevent {_received = (eventsequencestart nothing), _expected = nothing} "source" (line 1, column 1)

if move [^thanks] outside header, .pdf compiles there no footer on title page (nor anywhere else), , [^thanks] appears as-is on title slide.

how can add footnote/thanks section title slide?

you use inline note. regular footnote syntax [^note_call] , [^note_call]: note_content on new line. inline notes' syntax ^[note_content]

--- title: "title" author: "michael chirico^[these people gave me money], other authors" date: "february 10, 2016" output: beamer_presentation --- 

another solution allows more flexibility, restricted beamer output, change template.
