Replace cell values

[#1]

Hi,

I am trying to replace all the failing cells in the attached data table, which is highlighted in red with 1 and passing cells with 0. 

Found this but something doesn't work-

How do you get the color of a specific cell in a data table using JSL? 

Is there any better way to replace the cell values?

Here is what I tried

Names Default To Here( 1 );
dt = Current Data Table();
cols = dt << get column group( "Tests" );

get_cell_color = Function( {col, r}, 

	s = col << get script;

     //Locate argument "Color Cells" in column script

	For( i = 1, i <= N Arg( s ), i++, 

		If( Head Name( Arg( s, i ) ) == "Color Cells", 

			p = i;

			Break();

		)

	);

     //Identify the sublist that contains the color of row r

	L = Arg( Arg( s, p ), 1 );

	For( i = 1, N Items( L ), i++, 

		If( N Row( Loc( L[i][2], r ) ) == 1, 

			color = L[i][1];

			Break();

		)

	);

	color;

);

// 


test_cols = Transform Each( {col}, cols, col << get name );
dt << Select All Rows;
selrow = dt << get Selected Rows();
dt << begin data update;

For Each( {testcol, idx}, test_cols, 

	For Each( {ro, idx2}, selrow, 
	
		
		cellcolor = get_cell_color( Column( testcol ), ro );
		If( !cellcolor == 3, 
		
			Column( testcol )[ro] = 0
		
		)

		;
	)
);
dt << end data update;

Thanks,

How to get the row number of colored cells in a column and assign it a tag (say "1") in a newly crea... might provide other suggestion. With small modification to create_failed_column_after (you should also rename it) you can get it to update the values instead of creating new column with the values.

This is one way how you could modify the script found from that post

Names Default To Here(1);

get_colored_cells = Function({dt, colname}, {Default Local},
	colscript = Column(dt, colname) << Get Script;
	l = Substitute(Name Expr(colscript), Expr(New Column()), List());
	colored_cells = {};
	Try(
		colors = l["Color Cells"];
		If(Type(colors[1]) == "List",
			jmptrickery = 1,
			jmptrickery = 0
		);
		For Each({color}, colors,
			If(jmptrickery,
				Insert Into(colored_cells, color[2]),
				Insert Into(colored_cells, color)
			)
		);
	);
	Return(Matrix(colored_cells));
);

colored_to_pass_fail = function({dt, colname}, {Default Local},
	failed_rows = get_colored_cells(dt, colname);
	row_vals = J(1, N Rows(dt), 0);
	row_vals[failed_rows] = 1;

	Column(dt, colname) << set values(row_vals);
	// dt[0, colname] = row_vals`; // or data table subscripting
);

dt = Open("$SAMPLE_DATA/Big Class.jmp");

wait(1);
dt << Select Rows([4,5,6,7, 10,11, 14, 15]);
:height << Color Cells(3);
dt << clear select;
wait(1);


dt << Begin Data Update;
For Each({colname}, dt << Get Column Names("String", Continuous),
	colored_to_pass_fail(dt, colname);
);
dt << End Data Update;

wait(0);
