\usage{
subbars(term)
}
\arguments{
\item{term}{a mixed-model formula}
}
\value{
the formula with all | and || operators replaced by +
}
\description{
Substitute the '+' function for the '|' and '||' function in a mixed-model
formula. This provides a formula suitable for the current
model.frame function.
}
\section{Note}{
This function is called recursively on individual
terms in the model, which is why the argument is called \code{term} and not
a name like \code{form}, indicating a formula.

subbars(Reaction ~ Days + (Days|Subject)) ## => Reaction ~ Days + (Days + Subject)
