About the zlib licensed code:
Some of the C source code in src/ comes from zlib-derived library minizip (you
can check this by grep-ping minizip author's name like this  find src/ -exec
grep -nH Volland {} \; ). 
I'm not aware of how R handle C library linking but either it's possible to
dynamically link to minizip system library (and it's conflicts with our "don't
ship bundled system library" rule), or it's not or use an heavily customized
version of minizip and then it's a (partial ?) derivative work.

The main issue is that zlib and BSD are both non-copyleft licenses which
requires to keep the original notice, mentionning original authors and if
original sources were modified. It's feasible but differences between zlib/BSD
are not worth shipping two notices, you'd better stick to zlib (the maintainer
should not worry about compatibility with other third party-libraries).

As i said, the licensing issue by itself is not a blocker for inclusion in
Fedora but it should be sorted out.
