Dear all, I have a problem with creating a package using R CMD INSTALL. Assume that I want to create a package named Solvequations. I have 4 Fortran files: squareroot.f , cuberoot.f , quadequation.f and cubequation.f I want to create 2 shared object files, in particular cubequation.so and quadequation.so Manually, I often do the following R CMD SHLIB cubequation.f cuberoot.f R CMD SHLIB quadequation.f squareroot.f and then it generates files : cubequation.so and quadequation.so Now, for creating a package, I do not want to do manually R CMD SHLIB .... I just want to type R CMD INSTALL Solvequations and I still want two files cubequation.so and quadequation.so . How could I do it?
