Abstract: Many algorithms have been proposed for the computation of efficient designs of experiments. However, the available R packages for implementing these algorithms are limited. We introduce an R package OptimalDesign which provides a toolbox for the computation of D- , A- and IV-efficient exact and approximate designs of experiments on finite domains, for regression models with real-valued, uncorrelated observations. The package incorporates several algorithms based on significantly different principles, including search heuristics, state-of-the-art mathematical programming methods, and a combination of convex optimization methods. The algorithms are illustrated on selected computation problems in the optimal design of mixture experiments.
