\description{Hyperparameters for the EM algorithm.}
\section{Objects from the Class}{
  Objects can be created by calls of the form \code{new("FLXcontrol",
    ...)}. In addition, named lists can be coerced to \code{FLXcontrol}
  objects, names are completed if unique (see examples).
}
\section{Slots}{
  \describe{
    \item{\code{iter.max}:}{Maximum number of iterations.}
    \item{\code{minprior}:}{Minimum prior probability of clusters,
      components falling below this threshold are removed during the
      iteration.}
    \item{\code{tolerance}:}{The EM algorithm is stopped when the
      (relative) change of log-likelihood is smaller than \code{tolerance}.}
    \item{\code{verbose}:}{If a positive integer, then the
      log-likelihood is reported every \code{verbose} iterations. If 0,
      no output is generated during model fitting.}
    \item{\code{classify}:}{Character string, one of \code{"auto"},
      \code{"weighted"}, \code{"hard"} (or \code{"CEM"}),
      \code{"random"} or (\code{"SEM"}).}
    \item{\code{nrep}:}{Reports the number of random initializations
      used in \code{\link{stepFlexmix}()} to determine the mixture.}
  }
  Run \code{new("FLXcontrol")} to see the default settings of all slots.
