}
\arguments{
\item{ev}{List of explanatory variables provided to \code{\link{regress}} or \code{\link{logistic}}}

\item{cn}{Column names for all explanatory variables in the dataset}

\item{intv}{Interaction terms specified}
}
\value{
\code{vars} is a vector of right-hand side variables, possibly with interactions, \code{iv} is the list of explanatory variables, and \code{intv} are interaction terms
