\arguments{
\item{object}{a \code{\link{Heatmap-class}} object.}
\item{which}{is dendrogram put on the row or on the column of the heatmap?}
\item{k}{a matrix may be splitted by rows, the value identifies which row-slice.}
\item{max_height}{maximum height of the dendrograms.}
\item{...}{pass to \code{\link[grid]{viewport}}, basically for defining the position of the viewport.}

\details{

If the matrix is split into several row slices, a list of dendrograms will be drawn by
the heatmap that each dendrogram corresponds to its row slices.
