Add list to categorical DoE

Question

I've tried many iterations of including curly brackets, not including them, including quotes, etc., but can't figure out how to cast a list to a new DoE with jsl. The idea is to try and achieve something like what is below:

itemList = {"item 1", "item 2", "item 3"};

DOE(
	Custom Design,
	{Add Response( Maximize, "Y", ., ., . ),
	Add Factor( Categorical, itemList, "item", 0 ),
	Set Random Seed( 5111413 ), Simulate Responses( 0 ), Save X Matrix( 0 )}
);

Same with Parse(), or Parse( Eval(, or Eval( Parse(...

You are correct about the previous code not working.....I did not examine the results close enough.  But here is a piece of code that does work

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/big class.jmp" );
Summarize( dt, itemList = By( :sex ) );
Eval(
	Substitute(
			Expr(
				DOE(
					Custom Design,
					{Add Response( Maximize, "height", ., ., . ),
					Add Factor( Categorical, __list__, "Sex", 0 ),
					Set Random Seed( 5111413 ), Simulate Responses( 0 ), Save X Matrix( 0 )}
				)
			),
		Expr( __list__ ), itemList
	)
);

Hi @txnelson ,

Thank you very much for your reply. Did you try running that code? I just tried and still didn't get the list populating the DoE.

Names Default to Here (1);

itemList = {"item 1", "item 2", "item 3"};

DOE(
	Custom Design,
	{Add Response( Maximize, "Y", ., ., . ),
	Add Factor( Categorical, Eval(itemList), "item", 0 ),
	Set Random Seed( 5111413 ), Simulate Responses( 0 ), Save X Matrix( 0 )}
);
