[R-pkg-devel] R CMD check: Titles in README

[Uwe Ligges]

We had to install the most recent pandoc release as the old failed for 
the recent texlive release with rmarkdown.

Apparently pandoc gives a different error message for empty titles now. 
The simplest solution would be to provide a proper title anyway.

Best,
Uwe Ligges
