Using "Make Into Matrix" in JSL

shoffmeister — Tue, 11 Jul 2017 13:49:19 GMT

Hi folks,

I would like to extract a table out of a report (Multivariate -> Multivariate) into a matrix as part of my script. Currently I am working with this:

collist = {:"X1", :"X2", :"X3", :"X4", :"X5"};
 
cor = Eval(Eval Expr(Multivariate(
Y( Expr(collist)),
Estimation Method( "Row-wise" ),
Matrix Format( "Square" ),
Scatterplot Matrix( 0 )
)));
r = (col <<Report)[Outline Box("Correlations")][1][1] << Make into Matrix

Sadly there is no documentation (?) on the message "Make into matrix" and I cannot figure out how to store the resulting matrix in a variable without the dialog appearing.

For the moment I will work with "Make into Table". But it would be great to know how to use "Make into matrix".

Cheers,

Sebastian

This code will bypass the dialog box. It uses the standars and documented JSL components

names default to here(1);
dt=open("$SAMPLE_DATA\semiconductor capability.jmp");
collist = {:"NPN1", :"PNP1", :"NPN2", :"PNP2", :"NPN3"};
 
cor = Eval(Eval Expr(Multivariate(//invisible,
Y( Expr(collist)),
Estimation Method( "Row-wise" ),
Matrix Format( "Square" ),
Scatterplot Matrix( 0 )
)));
r = ((cor <<Report)[Outline Box("Correlations")][1][1] << Make into data table(invisible))<<get as matrix

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

multi var = dt << Multivariate(
	Y( :Age, :Weight, :Oxy, :Runtime, :RunPulse, :RstPulse, :MaxPulse ),
	Estimation Method( "Row-wise" ),
	Matrix Format( "Square" ),
	Scatterplot Matrix(
		Density Ellipses( 1 ),
		Shaded Ellipses( 0 ),
		Ellipse Color( 3 )
	)
);

multi var rep = multi var << Report;

corr = multi var rep["Correlations"][MatrixBox(1)] << Get;

Thanks a lot , Mark. That was just what I was looking for.

It's good that there are workarounds.

But, as Sebastian points out 'Make Into Matrix' does not appear in the Scripting Index as a message one can send to a 'MatrixBox()' (and the editor tooltip gives 'unknown message for object'). Yet it does appear as a context choice in the UI, and one can send the message via JSL (both giving the modal dialog he mentions).

Using Mark's (or JIm's) method, one could replicate the functionality of the dialog in scripting, but it's still a little strange.

I tried to apply this technique to the Bivariate Fit platform to retrieve Parameter Estimates. However the values are not in MatrixBox(1), but rather, they are in NumberColBox(13) and I get an error trying to retrieve them. I can manually store the entire set as a global variable and retrieve the values from the resulting matrix, but I haven't found any way to do that through jsl.

You can see all of the messages available to a Number Col Box() by going to

Help==>Scripting Index==>Number Col Box

you will see that a

obj << get

Will retireve the vector of data from a Number Col Box(). Or you may want to look one level up at the Table Box() object, which the Number Col Box() is an element of, and see what messages are available to it.

Thanks, your comments pointed me down the right path. It still seems not as elegant as the one-click method of storing the matrix as a global variable, but my script is working and that's what counts!
