Description Usage Arguments Value Author(s) References See Also Examples
This is a function to calculate the desirability for each response as well as the overall desirability.
The resulting data.frame
can be used to plot the overall as well as the desirabilities for each response.
This function serves for a visualization of the desirability approach for multiple response optimization.

overall
returns a data.frame
with a column for each factor, desirability for each response and a column for the overall desirability.
