Anything you put in the folder 'inst' of a package gets copied, as is,
to the installed package once 'everything else' is done (see section
1.1.3 of "Writing R Extensions" - which you read for caveats). Hence
you can create
- <arch> is either 'x64' or 'i386' (or both if you can compile for
both architectures) for 64 or 32 bit R respectively, and
- <package_name> is the name of the package.
Then as per section 1.6.3 of "Writing R Extensions" You can then add the line
to your NAMESPACE file and it should then work as before (noting that
you should use the PACKAGE argument in your .C, .Call and .External
calls to the routines therein). Optionally, you can list the symbol
names in the call to useDynLib as per section 1.6.3 of "Writing R
