exposition: Exposition pipe

In msmclear/magrittr: A Forward-Pipe Operator for R

Description

Expose the names in lhs to the rhs expression. This is useful when functions do not have a built-in data argument.

Usage

lhs %$% rhs

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.

  subset(Sepal.Length > mean(Sepal.Length)) %$%
  cor(Sepal.Length, Sepal.Width)
  
data.frame(z = rnorm(100)) %$% 
  ts.plot(z)
