Loop for column names doesn't work

[#1]

Hello,

I am novice in JSL. I try to do a Wilcoxon test for a range of columns. My first column is "ID" and second is "SEX" which I used as parameter.

So, I wrote the following code to do analysis and export results to a journal :

dt = Current Data Table();

column_names = dt << Get Column Names;

for(i=3,i<=length(column_names),i++,

ow = ow || "

            Oneway(

                Y( :Name(" || column_names || ") ),

                X( :SEX ),

                Wilcoxon Test( 1 ),

                Box Plots( 0 ),

                Mean Diamonds( 0 )

            ); "   

);

eval(parse(ow)) << Journal();

But it doesn't work and I don't know what is wrong with code.

I also have another question : "Is it possible to export only P value to a journal ? I used SendToReport (dispatch ..... ) but there are still section titles in results. What I need is only my column name and P value. Is it possible ?"

Please help me.

Thanks in advance

Try this:

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

column_names = dt << Get Column Names(numeric,String);

jw = New Window("demo",<<journal);

for(i=1,i<=NItems(column_names),i++,

  colName = column_names;

  cmd = Expr(

  ow = Oneway(

  Y( cName ),

  X( :SEX ),

  Wilcoxon Test( 1 ),

  Box Plots( 0 ),

  Mean Diamonds( 0 );

  );

  owr = ow<<report;

  owr << Outline Box(1) << Close;

  pValues = owr[TableBox(3)];

  jw << Append(ob = Outline Box(colName));

  ob  << Append( pValues );

  ob << Append( owr );

  ow << Close Window;

  );

  Substitute Into(cmd,Expr(cName),colName);

  Eval(cmd);

);

or if you just want the column name and p-value ....

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

column_names = dt << Get Column Names(numeric,String);

results = New Table("Results", invisible,

  New Column("Name", character),

  New Column("P-Value", numeric),

  Add Rows(NItems(column_names))

);

for(i=1,i<=NItems(column_names),i++,

  colName = column_names;

  cmd = Expr(

  ow = dt << Oneway(

  Y( cName ),

  X( :SEX ),

  Wilcoxon Test( 1 ),

  Box Plots( 0 ),

  Mean Diamonds( 0 );

  );

  owr = ow<<report;

  matPValue= owr[NumberColBox(11)];

  pValue = matPValue[1];

  Column(results,1) = colName;

  Column(results,2) = pValue;

  ow << Close Window;

  );

  Substitute Into(cmd,Expr(cName),colName);

  Eval(cmd);

);

results << journal;

Close(results);

Dear Dave,

Thanks a lot for your help. It really saved my time.

However, when I tried the second script, I got no answer so I changed the result table property to "visible" and I found out although it created right number of rows corresponding to number of columns I need to analyze, no data was injected in result table.

I appreciate if you give me a hint how to solve it.

Thanks in advance fo your valuable helps.

This is what the output should look like for the second script:

What version of JMP are you using?  I've run it successfully on v9 and v10.

Also take a look at the log file to see if you get any error messages.

The p-values are extracted by referencing the appropriate display box in the tree structure of the report using the following line of code:

matPValue= owr[NumberColBox(11)];

The name of the display box - NumberColBox(11) - is identified by looking at the tree structure ... so you could try this to verify that the display box name is correct:

after the line:

owr = ow<<report;

add:

owr << show tree structure;

which will give output something like this:

Dear Dave,

Thanks for your quick and detailed answer.

I work with JMP8 and it seems that the structure is a bit different. In my version  "NumberColBox(7)" refers to p value.

I also appreciate for your tip about how to see the tree structure. It is a great help.

Good Luck
