}
\arguments{
  \item{data}{
    A numeric vector, matrix, or data frame of observations.
    Categorical variables are not allowed.
    If a matrix or data frame, rows correspond to observations and
    columns correspond to variables.
  }
  \item{logarithm}{
    A logical value indicating whether or not the logarithm of the
    component densities should be returned.
    The default is to return the component densities,
    obtained from the log component densities by exponentiation.
  }
 \item{parameters}{
     The parameters of the model:
     \describe{
        \item{\code{mean}}{
              The mean for each component. If there is more than one component,
              this is a matrix whose kth column is the mean of the \emph{k}th
              component of the mixture model.
        }
        \item{\code{variance}}{
              A list of variance parameters for the model.
              The components of this list depend on the model
              specification. See the help file for \code{\link{mclustVariance}}
              for details.
            }
        \item{\code{pro}}{
               Mixing proportions for the components of the mixture. 
               If the model includes a Poisson term for noise, there 
               should be one more mixing proportion than the number 
               of Gaussian components.
          }
     }
  }
 \item{warn}{
    A logical value indicating whether or not a warning should be issued
    when computations fail. The default is \code{warn=FALSE}.
  }
 \item{\dots}{
    Catches unused arguments in indirect or list calls via \code{do.call}.
  }
}
\value{
  A numeric matrix whose \code{[i,j]}th 
  entry is the density of observation \emph{i} in component \emph{j}. 
  The densities are not scaled by mixing proportions.
}
\note{
  When one or more component densities are very large in magnitude,
  then it may be possible to compute the logarithm of the component
  densities but not the component densities themselves due to overflow.
