Expose the names in lhs
to the rhs
expression. This is useful when functions
do not have a built-in data argument.
Arguments
- lhs
A list, environment, or a data.frame.
- rhs
An expression where the names in lhs is available.
Details
Some 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.
