R devel - Oct 2008 - Dynamic linking to binary code from other packages??

Dear R-devel,

I am writing a package that needs some C++ functions from an external
SDK (Affymetrix fusion).  The same functions are already compiled into
another package (affxparser).

Can I dynamically link to the compiled code in affxparser, rather than
re-compiling these separately into my package?

Not a lot of experience on this subject!

Thanks,
Charles

Yes.  Working examples are lme4 using Matrix.  This is documented in the 'R
Extensions' manual.

I don't think it is the easiest way around.  Maybe start by 'just'
recompiling and relinking.
