Setting "ignore errors" flag on a formula column

Question

I have a formula column (confidence interval from the nonlinear platform) that sometimes generates an error during evaluation:

This error can not be captured in a Try() block.

My work around is to set the Suppress Eval flag and manually evaluate the formula one row at a time but I would prefer to be able to  set the "Ignore Error" flag on the column to suppress repeated error messages that occur.

I've not found a way to set this in JSL.  Any ideas?

Hi Gregg,

Could you see if you have ans to below exceptions for formula errors:

1. if it is not possible to pre catch the error. e.g my formula is a string and i will not know error untill i parse and eval the formula string.

2. when we run formula via button it does not send error to log instead it pops a window. And formula errors becomes monsters when you are creating 1000s formula columns and you get bombarded with pop error windows like spam.

Thanks for your help

Thanks Xan

The problem is that I am saving the formula from the nonlinear platform and the error gets raised during the save message - so I don't have time to inspect the formula to test for an error condition.  I'll take another look at how it behaves in JMP 12 Beta but from memory I wasn't able to "silence" the errors.

You've probably already tried this, but just in case: maybe you can pre-catch the error, such as

If( not symmetric(x), ., rest of formula(x))

If it's any consolation, the JMP 12 beta will turn on Ignore Errors automatically when you set a problem formula via script. I tried:

Column( "X" ) << Set Formula( If( Random Uniform( 0, 1 ) < 0.5, Foo(), 1 ) );
