\title{Check for the presence of an intercept in a formula or in a fitted
model}
\usage{
has.intercept(object, ...)
\method{has.intercept}{default}(object, ...)
\method{has.intercept}{formula}(object, ...)
\method{has.intercept}{Formula}(object, rhs = NULL, ...)
\method{has.intercept}{panelmodel}(object, ...)

}
\arguments{
\item{object}{a \code{formula}, a \code{Formula} or a fitted model (of class
\code{plm} or \code{panelmodel}),}
\item{\dots}{further arguments.}
\item{rhs}{an integer (length > 1 is possible), indicating the parts of right
hand sides of the formula to be evaluated for the presence of an
intercept or NULL for all parts of the right hand side
(relevant for the \code{Formula} and the \code{plm} methods)}
}
\value{
a logical
}
\description{
The presence of an intercept is checked using the formula which is
either provided as the argument of the function or extracted from
a fitted model.
