Hi @KevinBrunner ,
i would think the most obvious way of comparing columns (rather than rows) in JMP would be using table join.
perhaps something like this
// New data table
// ā Data Table( "Untitled" )
dt1 = New Table( "Untitled" );
dt1 << New Column("Column 1", Character, "Nominal", Set Values({"A", "B", "C", "D", "E"}));
// New data table
// ā Data Table( "Untitled 2" )
dt2 = New Table( "Untitled 2" );
dt2 << New Column("Column 2", Character, "Nominal", Set Values({"A", "E", "F", "B", "H"}));
// Join data tables
// ā Data Table( "Untitled 3" )
dt1 << Join(
With( dt2 ),
Match Flag( 1 ),
By Matching Columns( :Column 1 = :Column 2 ),
Drop multiples( 0, 0 ),
Include Nonmatches( 1, 1 ),
Preserve main table order( 1 )
);
it can also be done using clicking rather than scripting. as in the picture below
