\title{
  Fit one or more kinetic models with one or more state variables to one or more datasets
}
\description{
  This function calls \code{\link{mkinfit}} on all combinations of models and datasets
  specified in its first two arguments.
}
\usage{
mmkin(models, datasets,
      cores = round(detectCores()/2), cluster = NULL, ...)
}
\arguments{
  \item{models}{
    Either a character vector of shorthand names ("SFO", "FOMC", "DFOP",
    "HS", "SFORB"), or an optionally named list of \code{\link{mkinmod}}
    objects.
  }
  \item{datasets}{
    An optionally named list of datasets suitable as observed data for
    \code{\link{mkinfit}}.
  }
  \item{cores}{
    The number of cores to be used for multicore processing. This is only
    used when the \code{cluster} argument is \code{NULL}.
  }
  \item{cluster}{
    A cluster as returned by \code{\link{makeCluster}} to be used for parallel 
    execution.
  }
  \item{\dots}{
    Further arguments that will be passed to \code{\link{mkinfit}}. 
  }
}
\value{
  A matrix of \code{\link{mkinfit}} objects that can be indexed using the model
  and dataset names as row and column indices.
}
\seealso{
  \code{\link{[.mmkin}} for subsetting, \code{\link{plot.mmkin}} for plotting.
