[R] Functions in a package not visible to a user

[Roger D. Peng]

The old way was to define the internal functions inside the 
functions that used them.  Nowadays it's better to use a 
namespace.  `R CMD check' will only check code/docs for exported 
functions so non-exported/internal functions don't need to have a 
help file.
