Hello everyone,
I am working on a project that helps users to pick modules based on their input. For example, if user input 5, the script would give user 5 modules that been selected. Could anyone one help me with the "select" part?
This should work
Names Default To Here( 1 );
dt << Select Where( Column( "Shippable to Reliability?" )[Row()] == 1 );
dtsub = dt << Subset( Selected Rows( 1 ), Output Table( "Best Modules" ) );
dtsub << New Column( "random", formula( Random Uniform() ) );
dtsub = dtsub << sort( by( :random ), order( ascending ), replace table( 1 ) );
dtsub << select where( Row() > 5 );
dtsub << delete rows;
dtsub << delete columns("random");
Just for fun, an alternate method.
Names Default To Here( 1 );
dt = open("$sample_data/big class.jmp");
idx = Random Shuffle( dt << Get Rows Where( Column( "sex" )[]== "F" ) );
//get the matching rows but mix up the order;
show(idx); //for demonstration
//use only 5 of them
dtsub = << Subset( rows(idx[1::5]), Output Table( "Best Modules" ) );
