Hello, I am trying to determine if R has a package for generating covering arrays. I have done a general Google search as well as searched several R forums and help sites but have not been able to find anything definitive one way or the other. I know there are packages that have the ability to generate Orthogonal Arrays (e.g., DoE.base) but I am looking for the capability to generate Covering Arrays for some software testing (the main difference being in an orthogonal array, each combination occurs exactly x times, but in a covering array each combination occurs at least x times; a relaxing of the requirement that can make a difference in the ability to find a solution as well as in the size of the array). If anyone knows of a package for Covering Arrays, I would greatly appreciate the information.
