Up to a point:

1) See the manual about the concept of a name space.

2) A package can also have one or more private environments, using 
new.env() or local(): grDevices is an example.

However, R is Open Source so a determined user can find such 
environments: hence 'the user cant see whats in it' (is your ' key 
broken?) is not really achievable.
