The following example creates a new column called Floss Delimited 2, and adds a supercategory called Sleep Related, which contains two values: Before Sleep and Wake.
dt = Open( "$SAMPLE_DATA/Consumer Preferences.jmp" );
dt << New Column( "Floss Delimited 2",
Character,
Set Property(
"Supercategories",
{Group( "Sleep Related", {"Before Sleep,", "Wake,"} )}
), ...);
In the data table, under the Columns panel at left, scroll down to the new Floss Delimited 2 column. Click the column property indicator and select Supercategories. You can see the new Sleep Related supercategory with its two values.
dt = Open( "$SAMPLE_DATA/Consumer Preferences.jmp" );
dt << Categorical(
Supercategories(
:Floss Delimited(
{Group( "Sleep Related", {"Before Sleep,", "Wake,"} )}
)
),
Multiple Response( :Floss Delimited )
);
