My colleague and I are using the R library "AlgDesign" to D-efficiently block an existing design (which we have not computed through optFedorov).
Before proceeding with the blocking, we are coding the matrix design using a standardised orthogonal approach.
Since we are already passing to optBlock a coded matrix, we have silenced the lines of code in the source, which do the same job.
The requirements are that the D-efficiency of the blocked design should be greater than 0.90.
Is there a way to add this criterion to optBlock?
Could you please support us with this?

Thank you for your time and support.
