star-methods: Get and set methods
In qualityTools: Statistical Methods for Quality Science

function to set and get the star portion of a response surface design

## S4 method for signature 'facDesign'
star(x)
## S4 replacement method for signature 'facDesign'
star(x) <- value

`x`	a ‘facDesign’ object
`value`	`data.frame` holding the star portion.

signature(x = "facDesign"): Get and set the star for the factors in an object of class facDesign.
Could be used to exchange a default star portion with a specific one. So far used internally.

#rotatable response surface design with 3 factors
design = rsmDesign(k = 3) 
#star portion of the design
star(design)
