Delete Columns with Formula Reference in JSL

Hi,

I have a script where I would like to delete columns that contain a formula reference.  This is easy to do in JMP: when delete the unnecessary columns I get a "JMP Alert" and select "Remove Formula".  I am then able to delete my metadata columns, but the table maintains the result calculated in the formula column.

 

My problem is: how can I script this?  Is there an option to delete a metadata column that contains a formula reference?  I am using JMP10.  Please see the example below.

 

 

/*
bigClass = Open( "$SAMPLE_DATA/Big Class.jmp" );
bigClass << New Column( "height / weigh", Numeric, Continuous, Format( "Best", 12 ), Formula( :height / :weight ) );
bigClass << Delete Column( "height" );
bigClass << Delete Column( "weight" );
*/

 

 

Thanks!

Can you tell me how you solved this problem?  I have tried to remove formula, but this removed the values in the original column.  I need to delete a column contains a column reference.  Thank you.

Re: Delete Columns with Formula Reference in JSL

This is kind of old, but I have an addition to this and I figure I'll try here first

What if I don't know the columns with formula that will be referencing the column i want to delete. I am trying to make something dynamic, and I would like to precode it so it wilkl automatically delete the formula if there is a conflict (just like if i did it manually), but I can't find any syntax that allows for that.

 

the "easiest" method is to just remove all formulas so it's never an issue, but that seems a bit more extreme than it needs to be.
