AddListRemoveLabelGroup: Add / List / Remove global labelGroup to / of / from emuDB

In emuR: Main Package of the EMU Speech Database Management System

Add / List / Remove global labelGroup to / of / from emuDB

Description

Add / List / Remove label group that can be used as a short hand to reference groups of labels that are globally defined for the entire database (compared to attribute definition specific label groups that are added by add_attrDefLabelGroup) in a query. A common example would be to add a label group for something like the phonetic category of nasals to be able to reference them as "nasals" in a query. In theory you could use a labelGroupName as a label instance within the level, but since this could lead to serious confusion, it is better avoided. For users transitioning from the legacy EMU system: Do not confuse a labelGroup with legal labels: a labelGroup had the unfortunate name 'legal labels' in the legacy EMU system. For more information on the structural elements of an emuDB see vignette{emuDB}.

Usage

add_labelGroup(emuDBhandle, name, values)

list_labelGroups(emuDBhandle)

remove_labelGroup(emuDBhandle, name)

Arguments

emuDBhandle	emuDB handle as returned by load_emuDB
name	name of label group
values	character vector of labels
