Fortran file formats depend on the compiler and OS, neither of which you 
have told us.  You may be able to write a suitable file with writeBin: I 
would start by trying to read such a file with readBin.  Otherwise you 
link compiled Fortran into R to do this (if Fortran I/O works, again 
depends on your unstated system).
