\title{Extract number of intercepts}
\description{
Extract the number of intercepts from a model
}
\usage{
num.intercepts(fit, type=c('fit', 'var', 'coef'))
}
\arguments{
\item{fit}{a model fit object}
\item{type}{
the default is to return the formal number of intercepts used when fitting
the model. Set \code{type='var'} to return the actual number of
intercepts stored in the \code{var} object, or \code{type='coef'} to
return the actual number in the fitted coefficients. The former will be
less than the number fitted for \code{\link[rms]{orm}} fits, and the
latter for \code{orm} fits passed through
\code{\link{fit.mult.impute}}. If the \code{var} object is not present, the number of intercepts is determined from the \code{ab} element of the \code{info.matrix} object if it is present.
}
}
\value{
\code{num.intercepts} returns an integer with the number of intercepts
in the model.
