\title{Estimation of parameter distributions from mmkin row objects}
\usage{
memkin(object, ...)
}
\arguments{
\item{object}{An mmkin row object containing several fits of the same model to different datasets}
\item{...}{Additional arguments passed to \code{\link{nlme}}}
}
\value{
A fitted object of class 'memkin'
}
\description{
This function sets up and attempts to fit a mixed effects model to
an mmkin row object which is essentially a list of mkinfit objects
that have been obtained by fitting the same model to a list of
datasets.
