Dear everybody, I have 20 levels of a factor. I want to create 1000 combinations of 6 different levels of that factor so that each level is repeated about the same number of times (across 100 combinations) and so that the number of times level X is combined with level Y is also about the same (across 1000 combinations). So, it's an experimental design question. I don't think I can use algDesign for that.
Any other hints?
