A synchronization flag

The inert function sync() operates analogously to ggplot2::waiver() to indicate that an auxiliary aesthetic should be synchronized to a standard aesthetic (when it is mapped from data). is.sync() reports whether an object is of this class.

Usage

sync()

is.sync(x)

Arguments

x

An object to test

Value

sync() returns an empty list with the "sync" class; is.sync() returns a logical value of whether x inherits this class.
