How to select my main data table

Question

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?

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 )
	);
);

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?
