LAPACK is in Fortran. See `Writing R Extensions' from the definition of what $(LAPACK_LIBS) provides, and for details of the corresponding C headers.

There are lot of examples amongst CRAN packages of calling LAPACK from C.

I have a c code which uses clapack. I want to integrate R with this code. It
said that I create a R package including my c code. Then build it with putting
PKG_LIBS = $(LAPACK_LIBS). I want to know the interface LAPACK_LIBS is Fortran
or C? If it is written in Fortran, how can I build them together? If I can
build them together, I still use the function in cLapack or the function in
LAPACK_LIBS? Could you tell me how I can do in detail?
