Hello, While looking for info on 2^k experimental design and anova I remember I saw somewhere there was a function to generate all the experiments. I can't find the function anymore can anyone suggest? The function takes as input the factors and levels and generates all the experiments. I know I can do it myself using recursion but I want to avoid 1) reinventing the wheel and 2) making mistakes while at it. TIA, Best regards, Giovanni

Check out the Task View on Experimental Design: http://cran.at.r-project.org/web/views/ExperimentalDesign.html but perhaps packages rsm or qualityTools have what you want. Bryan *********** Bryan Hanson Professor of Chemistry & Biochemistry DePauw University

Never mind, found it, it is the expand.grid function.
