How do I associate three different columns together using namespace?

[#1]

I have three columns of data that I want to associate each row with each other. I was looking at namespace since I have to return a list back to another file. (Assuming I can use one singular list of lists within it to select the rows of data). If this is not the best way to do it (as a result of being too messy or better ways to do it). How can this be achieved?

Below is what I have so far, the code only associates two columns together. I'm not sure on how to associate the third. Ideally I would like to associate group2 with group3.

NS = New Namespace();

group1 = column("group1")<<GetAsMatrix();
group2 = column("group2")<<GetAsMatrix();
group3 = column("group3")<<GetAsMatrix();
		
NS:group2 = groups;
for(i=1, i<=N Items(group1), i++,
NS:(group2[i]) = group1[i];
);

I don't think you need to use a namespace to accomplish this, maybe just building a list of lists will do what you want. Is this moving the right direction?

Names default to here(1);

dt = Open("$Sample_data/iris.jmp");

NS = New Namespace();
col = {};
col[1] = column(dt, "Sepal Length");
col[2] = column(dt, "Sepal Width");
col[3] = column(dt, "Petal Width");

// if you have JMP 16:
coldata1 = transform each ({c}, col, c << GetasMatrix());

// JMP 15 and older:
coldata2 = {};
for(i=1, i<=n items(col), i++,
	coldata2[i] = col[i] << GetasMatrix()
);

// Either way you get the same result:
Show(coldata1 == coldata2);

// All data is in one object you can return to another script:
Show(coldata1);

This works - thank you!

If this is in a function, how can I return the list? Im not familiar with the syntax on JSL.

Just make that variable the last line in the function, something like this:

Names default to here(1);

myfunction = function( {},
	dt = Open("$Sample_data/iris.jmp");

	NS = New Namespace();
	col = {};
	col[1] = column(dt, "Sepal Length");
	col[2] = column(dt, "Sepal Width");
	col[3] = column(dt, "Petal Width");

	// if you have JMP 16:
	coldata1 = transform each ({c}, col, c << GetasMatrix());

	// JMP 15 and older:
	coldata2 = {};
	for(i=1, i<=n items(col), i++,
		coldata2[i] = col[i] << GetasMatrix()
	);

	// Either way you get the same result:
	Show(coldata1 == coldata2);

	// Return the list of lists:
	coldata1
);

show(myfunction());
