[R] searching for industrial experimental design in R
Hi all, I''ve toured the archive and the contributed pages, but didn''t find much new on industrial experimental design. Would anyone of you have written such routines and would you be willing to share? These are the elements I need: 1. An algorithm which finds the extreme vertices, edge centers, face centers, etc ... For a domain under equality and inequality constraings (constrained mixture type). 2. An algorithm for finding appropriate points in a candidate list. (I am aware of the dopt contributed package which could handle this for me) 3. Graphics for inspecting and exploring the resulting designs. Any hints are welcome as long as they are R based ... I have several other software solutions to this problem, but I''m specifically looking for an R one.
