Details

Units can be passed either as name=value pairs or as a named list with st_args(). Units can alternatively be passed as an argument to stable() as a pre-formed, named list using st_args(). Passing as an argument this way will overwrite units specified with st_units(). It is recommended to use either st_units() or st_args() but not both.
