Don, et al.: Further research led me to re-read the beginning of "Analyzing Compositional Data with R" where the authors describe the masking as analgous (my interpretation) to instatiating an object as in Python or wxPython. With the package compositions, there are functions with the same name as functions in other packages. The compositions package extends functionality and implies that the parent functionality is inherited, not replaced. Perhaps this is the norm for all R packages.
