 #' @param linearOnly Logical: If \code{TRUE} (default) then models with only linear terms are included in final set (plus other kinds of models if desired).
 #' @param quad Logical: If \code{TRUE} (default), then include quadratic terms.
 #' @param ia Logical: If \code{TRUE} (default), then include 2-way interaction terms.
-#' @param verboten Character vector of terms that should not appear in the models. Ignored if \code{NULL} (default). You can use this argument, for example, to exclude specific interactions (e.g., \code{'x1:x2'}, but also include the converse, \code{'x2:x1'}), or power terms (e.g., \code{'I\\(x1\\^2\\)'}). Note that to ensure matching, you need to use double backslash in front of parentheses and the caret (\code(^)) characters.

 #' @param verbotenCombos List of lists: Used to specify specific combinations of terms that should not occur together. See \emph{Details} below. Ignored if \code{NULL} (default).
 #' @param minTerms Either a positive integer representing the minimum number of terms required to be in a model, \emph{or} \code{NULL} (default) in which case the smallest model can have just one term.
 #' @param maxTerms Either a positive integer representing the maximum number of terms allowed to be in a model, \emph{or} \code{NULL} (default) in which case there is no practical limit on the number of terms in a model.
