When operating on an ungrouped object,
mutatewill use methods from {plyranges} but when operating on a grouped object,mutatewill rely on vanilla tidyverse by converting the object to a tibble. The result is then coerced back toDataFrameto update the metadata of the object. Of note, core columns can be used in this framework to create new metadata columns.
