There isn't a daemon to speak off, they are shared libraries that you load and call functions on.

I don't know much about R, but if it considers the whole memory space of the R process, it probably counted the memory consumption of the libraries themselves as well.

The memory profiling only measures allocations on the R heap (i.e. objects managed by R's GC). It doesn't measure allocations by other libraries running in the the same process, unless they use R's allocation machinery.
