## Selecting Multiple Columns in a Script

I have been working on a script to evaluate some possible transformations for fit for both first order and second order polynomials. The script seems to work well. However, I can only select one column at a time. Is there a way to change this script to allow for more than one column to be evaluated at a time?

``````Clear Log();
dt = Current Data Table(); // Use Current Data Table;
xvar = .;
yvar = .;
win = New Window( "Transformation Variable Selection",
<<Modal,
<<On Validate(
// require the user to select two variables before clicking OK
Show( xvar, yvar );
If( Is Missing( xvar ) | Is Missing( yvar ),
// if xvar or yvar are missing do nothing when OK is clicked
0

1

// get the name of the selected column before the window closes
Show( xvar );

dt,
all,
yvar = (y << Get Selected)[1];

## Re: Selecting Multiple Columns in a Script

Here's another approach to the dialog that lets the user select one or more columns for X and Y. This returns a list of columns for each role. With multiple columns selected, though, the remainder of your script will need to do additional processing of the list to retrieve the columns before looping through the transformations - you may need to add another level of iteration.

``````Names Default To Here( 1 );
dt = Open( "\$SAMPLE_DATA/Body Fat.jmp" );
win = New Window( "Transformation Variable Selection",
<<Modal,
Text Box( "Available Columns" ),
H List Box(
// list box to present cols
allcols = Col List Box( dt, all ), // or specify numeric instead of all
Lineup Box(
2,
bbx = Button Box( "X, Factor", xcols << append( allcols << get selected ) ),
// list box to receive cols
xcols = Col List Box( "Numeric", <<Modeling Type( {"Continuous"} ), min items( 1 ) ),
bby = Button Box( "Y, Response", ycols << append( allcols << get selected ) ),
// list box to receive cols
ycols = Col List Box( "Numeric", <<Modeling Type( {"Continuous"} ), min items( 1 ) )
),
V List Box(
bbOK = Button Box( "OK",
xvar = (xcols << Get Items);
yvar = (ycols << Get Items);
// Show( xvar, yvar );
),
bbCancel = Button Box( "Cancel" )
)
)
);
// stop the script if user chooses Cancel
If( win["Button"] == -1,
Throw( "User Cancelled" )
);``````

## Re: Selecting Multiple Columns in a Script

When getting the column names from the Col List Box in your script, you subset the list that is returned with [1].  This only returns the first selected column.  If you remove the brackets and then iterate over the lists you can apply your script to multiple x and y column pairs.  You likely want to summarize or concatenate your results but the basic idea would look like the script below. Note that to speed things up I only evaluate a=1 (see the commented /* 7 */)

``````Names Default To Here( 1 );

//wrap your script to process both variables in a function
//this is not necessary but it make the new for loops more clear
processpair = function({dt, xvar, yvar},
d = 1;
m = Matrix( 72, 5 );
l = List( 72 );
l1 = List( 72 );
l2 = List( 72 );
For( c = 1, c < 3, c++,
For( b = 1, b < 7, b++,
transb = Match( b, 1, "Log", 2, "Sqrt", 3, "Square", 4, "Reciprocal", 5, "Exp", 6, "None", );
For( a = 1, a < 7 /* 7 */, a++,
transa = Match( a, 1, "Log", 2, "Sqrt", 3, "Square", 4, "Reciprocal", 5, "Exp", 6, "None", );

## Re: Selecting Multiple Columns in a Script

Whenever I remove the [1] (see underligned and italicized in the script below) from the portion of the script below, it doesn't work.  The script you provided does not allow me to click okay on the text box and therefore doesn't actual run the bivariate portion of the script.

I don't mean to be a pain, I am still trying to get a handle on JSL. Any help you can provide would be greatly appreciated.

H List Box(

Text Box( " X, Factor " ),

x = Col List Box(

dt, // data table reference

all, // display all columns from the data table

xvar = (x << Get Selected)[1];

// get the name of the selected column before the window closes

Show( xvar );

),

Text Box( "Y, Response" ),

y = Col List Box(

dt,

all,

yvar = (y << Get Selected)[1];

Show( yvar );

## Re: Selecting Multiple Columns in a Script

Sorry about that, there were a few bugs in that script.  Here is something closer to how I would implement this:

``````Names Default To Here( 1 );

For (FitDegree = 1, FitDegree <= 3, FitDegree++,

biv = dt << Bivariate(
Y( Column( yvar ) ),
X( Column( xvar ) ),
Fit Special(
xTran( transformations[transx] ),
yTran( transformations[transy] ),
Degree( FitDegree ),
//Centered Polynomial( 1 ),
{Line Color( {212, 73, 88} )}

rbiv = Report( biv );
bivmatrix = Try( rbiv[Outline Box( 3 )][1][2] << Get As Matrix );
If( Is Missing( bivmatrix = Try( rbiv[Outline Box( 3 )][1][2] << Get As Matrix ) ),	0 );
