R package and MiSa.C separation

The reason is that the R package installation is tarting to get overloaded. There are too many dependencies that make the installation process slow and increases the potential of conflicts. For example, under Linux operating systems all the R dependencies require specific Linux libraries to be compiled. I got reports that user stop installing HaSa package under Linux since there are too many Linux compile processes required. Even on Windows it takes 5-10 minutes to install HaSa which is unusual for R packages.

I have the feeling that there are many R dependencies integrated that are used only by MiSa.C or I am wrong? So my question, would it make sense at a certain point to stop adding more and more dependencies to the R package that are not really needed for executing the algorithm itself and provide a minimalistic stable version of an R package that is then only updated if the algorithm itself is changed?

I have the feeling that the R-package is already unnecessarily big with regard to dependencies!
