Expose the names in lhs to the rhs expression. This is useful when functions
do not have a built-in data argument.
lhs %$% rhsSome functions, e.g. lm and aggregate, have a
data argument, which allows the direct use of names inside the data as part
of the call. This operator exposes the contents of the left-hand side object
to the expression on the right to give a similar benefit, see the examples.
