yml_replace() replaces a named field with another value. As opposed to
duplicating top-level fields with other functions, explicitly replacing them
with yml_replace() will not raise a warning. yml_discard() removes values
given either a character vector of names or a purrr-style lambda with a
predicate (~ predicate); see the examples. yml_pluck() and yml_chuck()
are wrappers around purrr::pluck() and purrr::chuck() that return yml
objects.
yml_replace(.yml, ...)

yml_chuck(.yml, ...)a yml object created by yml(), as_yml(), or returned by
a yml_*() function
additional named R objects, such as characters or lists, to transform into YAML
a character vector of fields to remove or a purrr-style lambda
with a predicate (~ predicate) where fields that are TRUE will be
discarded
