    use PDL::Factor ();
    # extract levels from input
    my $blood_types = PDL::Factor->new( [ qw(B A AB A B A B O AB O) ] );
    # explicitly specify levels
    my $blood_types2 = PDL::Factor->new( [ qw(B A AB A B A B O AB O) ],
                                         levels => [ qw(A B AB O) ] );

METHODS

new( $data, %opt )

levels => $array_ref

    $c = $a->glue($dim, $b, ...);

Glue two or more PDLs together along an arbitrary dimension. For now it only supports 1D PDL::Factor piddles, and $dim has to be 0.
