[R] Truetype and Opentype font in pdf device

[Kohske Takahashi]

Thanks for the reply.

I got that there is no general way to generate PDF with ttf or otf
fonts. Thanks, it's enough.

Also, cario_pdf is useful (I'm using OSX).
But I found it cannot correctly(?) work with CJK.
I will play with them some more.

Thanks again.
