Beginner JSL query

[#1]

I want to save selected rows from a table in a jmp file and also the inversion of the selected rows in another jmp file after using the partition function. I went through some examples and other threads but I am not able to save the selected rows and the inverted rows. I must be doing something wrong. Does anyone have any idea how it can be done in JSL?

Names Default To Here( 1 );
dt = Open( "C:/Users/Desktop/driver/MASTER.jmp" );
f = Function({a}, theRows = Current Data Table() << get selected rows;
Show(theRows);

);
obj = Partition(

       Y( :Failed ),

       X(
             :VOLUME,

             :FAMILY,

             :CONFIG

       ),

       Method( "Decision Tree" ),

       Validation Portion( .2 )

);

obj << ShowGraph( 0 );

obj << SplitBest( 4 );
 
obj << on close( Clear Symbols( rs ) );

 

action = 0;

actionsubset = 0;

 

look_window = New Window( "Decision",

       Lineup Box( N Col( 1 ),

             V List Box(

                    Text Box( "After selection of the rows,go for Plot?" ),

                    H List Box(

                          spacer box(size(100,5)),

                          Button Box( "Continue",

                                 action = 1;

                                 look_window << close window;

                                 //obj << Save( "C:\Users\Desktop\test.csv" );

                                 //filepath = "C:\Users\Desktop\driver";

                                 //rs << save( filepath || "\" || "p1.jmp" );

                                

                                 Include("C:/Users/Desktop/driver/plot.jsl");

                                

                          ),

                          Button Box( "Close",

                                 action = 2;

                                 Close( obj, nosave );

                         

                                 //Throw( "You cancelled the script." );

                          ),

                    )

             ),

 

       )

);

The first item I can see, is that you are setting the variable "obj" to be a pointer to the output report for the Partition platform, and then in the New Window, you are using "obj" as if it is a pointer to your data table.  The pointer to your data table is the variable "dt" created when you opened the table.

Below is a simple example that shows a simple way to create a data table from selected rows, and then to create another data table from the inverse of that selection

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/big class.jmp" );

dt << select where( :sex == "F" );

dtF = dt << subset( selected rows( 1 ), selected columns( 0 ) );

dt << invert row selection;

dtM = dt << subset( selected rows( 1 ), selected columns( 0 ) );

close( dt, nosave );
