[R] embed latex beamer sans serif default font into R plot

[Kwok, Heemun]

Hello,
I have seen instructions on how to embed Latex Computer Modern fonts into R, but these are the default serif fonts. I am trying to embed the default font used for Latex beamer (theme Warsaw), which is a sans serif font and may be the default LateX Computer Modern sans serif font.    Does anyone know the names of the font files?
 
Thanks
Heemun
