Stacking Columns in Script

jmp_jr — Mon, 26 Apr 2010 17:31:17 GMT

I have a couple of questions about stacking data columns in a script. When I do it manually, I get the following script from JMP:

Data Table( "Untitled 11" ) << Stack(
columns(
:Name( "EFL 20508-17DT_CG_100ms" ),
:Name( "FFL 20508-17DT_CG_100ms" ),
:Name( "EFL 20508-18DT_CG_100ms" ),
:Name( "FFL 20508-18DT_CG_100ms" ),
:Name( "EFL 20508-19DT_NOCG_2" ),
:Name( "FFL 20508-19DT_NOCG_2" )
),
Source Label Column( "Label" ),
Stacked Data Column( "Data" ),
Number of Series( 2 )
)

In my script, I have a list variable (MyList1) containing the column names, and I would like to stack those columns using "Multiple Series Stack" to create a new table. Also, for "Number of Series" I would like to include NItems(MyList2). Can someone help me with the syntax?

I think this should work:

StackDT = SplitDT << Stack( Columns( MyList1 ),
Source Label Column( "Source" ),
Stacked Data Column( "Data" ),
Number of Series( NItems( MyList2 ) )
)
);

but it gives me "Column not found in access or evaluation of 'Bad Argument' " in the log.

I think

Columns(eval(MyList1))

should work.

You might want to call tech support and report it as a bug, or suggestion.

Yes. Evaluating the list does make it work. The list used for "Number of Series" also has to be evaluated.

Thanks for the reply.

I have a related question about stacking columns. I have been given an Excel spreadsheet that I need to turn into something useful. The spreadsheet looks like this:

style="font-family: Courier New; font-weight: bold; text-decoration: underline;">IDNo  Ctry
Sub  Sub
Date  Ctry  Sub  Sub
Date Ctry  Sub  Sub Date

style="font-family: Courier New;">
a123  US
N              Can
Y    4/1/2010  Braz
Y    3/15/2009

style="font-family: Courier New;">
b567  US

Y    5/1/2009  Can
N
Braz N

style="font-family: Courier New;">
c392  US

Y    6/1/2008  Can
Y    3/2/2001  Braz
Y    12/15/2008

etc.

I need to stack the results so they look like this:

style="font-family: Courier New; font-weight: bold; text-decoration: underline;">IDNo
Ctry Sub  Sub Date

style="font-family: Courier New;">
a123
US    N

style="font-family: Courier New;">
b567
US    Y
5/1/2009

style="font-family: Courier New;">
c392
US    Y
6/1/2008

style="font-family: Courier New;">
a123
Can
Y    4/1/2010

style="font-family: Courier New;">
b567
Can   N

style="font-family: Courier New;">
c392
Can
Y    3/2/2001

style="font-family: Courier New;">
a123
Braz Y    3-15-2009

style="font-family: Courier New;">
b567
Braz N

style="font-family: Courier New;">
c392
Braz Y    12/15/2008

In the real table there are about 20 countries going across. Is this something that the STACK command can handle? I.e. instead of just stacking one column, I need to stack three columns at once.

Thanks,
Peter

Yes. Look up Multiple Series Stack in the docs. There seems to be a minor bug which results in stacked date columns in multiple series stacking not being formatted as dates so you'll have to apply that format after stacking. Single column stacking of dates does maintain date format. You will also have to clean up some extra columns that result from the stacking.

Thanks that worked perfectly! This will save us a tremendous amount of time.

Maybe I can append a further question:

I want to stack several columns, column wise. This is easy going the menu way - simply by unchecking 'Stack by Row'. But I have not found an equivalent option on the stack scripting command.

Is it intended to go the cumbersome way to first create a transposed intermediate table, and then applying the stacking on that one?

You simply add "Stack By Row(0)" to your Stack message. Here's an example:

<--
Data Table( "Solubility" ) << Stack(
columns(
:Name( "1-Octanol" ),
:Ether,
:Chloroform,
:Benzene,
:Carbon Tetrachloride,
:Hexane
),
Source Label Column( "Label" ),
Stacked Data Column( "Data" ),
Stack By Row( 0 )
)
-->

Glad to here that. I expected something like this, but was unable to retrieve this information from anywhere within the documentation.

Thank you.

I'm glad that will help.

In a case like this, it's easiest to perform the action interactively by clicking and then examine the "Source" script in the resulting table.

please note that in JMP9 if you fail to generate correctly the list it will crash totally

for example this wil do:

listaNDD = {"5932_NDD","6038_NDD"};

def5932_NDD = {"chips","bubbles"};

def6038_NDD = {"big on top","small on top"};

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

a=listaNDD;

c=Concat(a,"_stacked");

d=Concat("def",a);

Open( Concat(a,".jmp"), invisible );

Open( b, invisible );

Data Table( a ) << Stack(

columns((d)),

Source Label Column( "class" ),

Stacked Data Column( "density" ),

Name( "Non-stacked columns" )(Keep( :Split, :Lot ID, :WID)),

Output Table( c )

);

because d it's not the list but a variable containing the name of the list ...
