How to select my main data table

[#1]

Hello,

So I'm working on a data table and I made a script to make several subsets of it. I'm going through a for loop to automate some modeling analysis. the first iteration goes well : do the subest, launch a fit model in the subset.

But then in the second iteration of the loop, it doesn't work anymore, because the selected table is the subset and not the main table. I can't find the right commands to assigm the current data table to my original table. Any ideas?

Are you referring to your data tables by name, or are you working with the current data table? In other words, does your script look like this:

dt = Open( "data table.jmp" );

dt2 = dt << Subset( ... );
dt2 << Fit Model( ... );

dt << subset( ... );

or like this?

Open( "data table.jmp" );

Subset( ... );
Fit Model( ... );

subset( ... );

or, perhaps something completely different?

You need to either assign a variable to reference the main table, or reference it using it"s name

Names Default To Here( 1 );
dt = 
// Open Data Table: big class.jmp
// → Data Table( "big class" )
Open( "/C:/Program Files/SAS/JMPPRO/16/Samples/Data/big class.jmp" );

ages = Associative Array( dt:age ) << get keys;

For Each( {year}, ages, 

	dt << select where( :sex == "F" & :age == year );
	dt << Subset(
		Selected Rows( 1 ),
		,
		Selected columns only( 0 )
	);
);

Or

Names Default To Here( 1 );
// Open Data Table: big class.jmp
// → Data Table( "big class" )
Open( "/C:/Program Files/SAS/JMPPRO/16/Samples/Data/big class.jmp" );

ages = Associative Array( data table("big class"):age ) << get keys;

For Each( {year}, ages, 

	Data Table( "big class" ) << select where( :sex == "F" & :age == year );
	Data Table( "big class" ) << Subset(
		Selected Rows( 1 ),
		,
		Selected columns only( 0 )
	);
);
