Notes on Use of Table Functions and Row Labels
• You cannot stack or unstack row labels using the stack and unstack functions. However, you can
use row labels as grouping variables.
• You cannot perform a join using the join, innerjoin, or outerjoin functions when the first
argument is a table and the second argument is a timetable. However, you can perform a join
when both arguments are tables, both are timetables, or the first argument is a timetable and the
second is a table.
• The output of a join operation can have row labels if you specify row labels as key variables. For
more details on row labels from a join operation, see the documentation on the 'Keys',
'LeftKeys', and 'RightKeys' arguments of the join, innerjoin, and outerjoin functions.
