Create a waiver object.

new_waiver()

Value

Object of class Waiver.

Details

This object is used to represent that the user has not manually specified a setting, and so defaults should be used. By explicitly using a new_waiver(), this means that NULL objects can be a valid setting. The use of a "waiver" object was inspired by the ggplot2 package.

Examples

# create new waiver object
w <- new_waiver()

# print object
print(w)
#> list()
#> attr(,"class")
#> [1] "Waiver"

# is it a waiver object?
is.Waiver(w)
#> [1] TRUE
