I am trying to use the coXpress function from the coXpress package. This function requires numerical vectors indicating which columns are in which group. The problem is, I can only figure out how to get a logical structure, not a numerical one. In other words, coXpress wants something like: "1:3" I have something like: TRUE TRUE TRUE FALSE FALSE Can I convert one into the other easily?
