A vectorized version of the library function that accepts one or
more package names to call library on. Unlike library,
the libraries function does not use non-standard evaluation (NSE)
on its inputs, meaning that you must supply your package names as strings,
or as variables.
Usage
libraries(...)
Arguments
...
one or more package names or package_obj objects
Details
You may supply either package names and package_obj objects to this
function. You may also add :: to the end of a package name to load
the package instead of attaching the package (this means that the package
will not be added to the search list, but will be available to access via
the :: operator).
