My understanding is that this cannot be done, for both licence and security
reasons. The package build expects source code and removes binaries. You can
link with binaries that are provided separately from the package, possibly
coming from a vendor that sells non-open source code, but you cannot include
them in the package.
Actually, you can include them, but then the package won't be accepted
on CRAN, for example.
Let me cite Writing R Extensions:
"Note that CRAN does not accept submissions of precompiled binaries due
to security concerns, and does not allow binary executables in packages.
Maintainers who need additional software for the Windows binaries of
their packages on CRAN have three options
1. To arrange for installation of the package to download the additional
software from a URL, as e.g. package Cairo does.
2. To negotiate with Uwe Ligges to host the additional components on
WinBuilder, and write a ‘configure.win’ file to install them. There are
many examples, e.g. package rgdal."
So in case you do not want to move it to CRAN, you can simply use the
same tricks that rgdal uses for Windows binaries on CRAN.

Subject: [Rd] Building R package with precompiled shared library
Dear R users,
we are trying to build a R package that includes a precompiled shared
library, let's say mylib.so. We created the skeleton of the package
and we moved the mylib.so file into the libs folder that we created at
the same level of the folders man and R. Moreover we created the file
NAMESPACE and we added the line useDynLib(mylib, .registration=TRUE).
The building step seems to work correctly but when we try to install
the package we get
** testing if installed package can be loaded
Error in library.dynam(lib, package, package.lib) :
shared library 'mylib' not found
we cannot understand what's wrong and where R searches for the mylib.so
files.
Any suggestion?
Thanks,
Michela and Francesco
