How to parse Design Role property with a script

I need to be able to identify which columns in a DOE data table are factors. I know there is a design role column property.

column(dtDOE, 1) << get property("Design Role");

The problem is that the return value seems to be an unevaluated expression.

DesignRole( Continuous )

Is Missing doesn't work in this context, but even if it did, I want to exclude blocking factors, so I need to somehow parse this thing.

Try using Arg()

drole_prop = Column(dt, "weight") << Get Property("Design Role");
drole = Arg(drole, 1); // "Continuous"
// Head(drole);&nbsp;//&nbsp;will&nbsp;get&nbsp;the&nbsp;outside&nbsp;expression,&nbsp;Design&nbsp;Role&nbsp;in&nbsp;this&nbsp;case

Note for me design role seems to contain a string so you might have to do some extra tricks to get the "something" type to string

Design Role("Continuous")

Thanks @jthi !

I am able to get the result as a string with

char(arg(drole,1))
