\usage{
decorate_heatmap_body(heatmap, code,
slice = 1, row_slice = slice, column_slice = 1,
envir = new.env(parent = parent.frame()))
}
\arguments{
\item{heatmap}{Name of the heatmap which is set as \code{name} argument in \code{\link{Heatmap}} function.}
\item{code}{Code that adds graphics in the selected heatmap body.}
\item{slice}{Index of the row slice in the heatmap.}
\item{row_slice}{Index of the row slice in the heatmap.}
\item{column_slice}{Index of the column slice in the heatmap.}
\item{envir}{Where to look for variables inside \code{code}.}
}
\details{
There is a viewport for each slice in each heatmap.
This function contructs the name of the viewport,
goes to the viewport by \code{\link[grid:viewports]{seekViewport}}, runs the code
to that viewport and finally goes back to the original viewport.
}
\value{
This function returns no value.
