如何加载一个包，以便需要使用命名空间引用符号？

Question

How can I load a package but not put everything that it exports into the "main namespace"?

library(myPackage) # exports myVar
myVar            # This works, but I want it not to work
myPackage::myVar # This works, and I do want it to work

Answer 1

For accessing the exported variables in a package, :: is sufficient. You don't need to load the package for this syntax to work. As ?":::" points out in the first paragraph of the Details section, the triple colon suggested by @csgillespie is intended for inspecting internal variables not exported by a package.
