A _15 second_ search of Writing R Extensions reveals this in Section 1.1.5:

      The sources and headers for the compiled code are in 'src', plus
   optionally a file 'Makevars' or 'Makefile'.  When a package is installed
   using 'R CMD INSTALL', 'make' is used to control compilation and linking
   into a shared object for loading into R. There are default 'make'
   variables and rules for this (determined when R is configured and
   recorded in 'R_HOME/etcR_ARCH/Makeconf'), providing support for C, C++,
   FORTRAN 77, Fortran 9x(5), Objective C and Objective C++(6) with
   associated extensions '.c', '.cc' or '.cpp', '.f', '.f90' or '.f95',
   '.m', and '.mm', respectively.  We recommend using '.h' for headers,
   also for C++(7) or Fortran 9x include files.  (Use of extension '.C' for
   C++ is no longer supported.)  Files in the 'src' directory should not be
   hidden (start with a dot), and hidden files will under some versions of
   R be ignored.
   
      It is not portable (and may not be possible at all) to mix all these
   languages in a single package, and we do not support using both C++ and
   Fortran 9x.  Because R itself uses it, we know that C and FORTRAN 77 can
   be used together and mixing C and C++ seems to be widely successful.

Note the second paragraph:  So f90 and C++ do NOT go together.
