\title{Subjects dendrogram}
\description{Get dendrogram for subjects (observations) based on variables of mixed data types}
\usage{
dendro.subjects(data, weights, linkage="ward.D2")
}
\arguments{
\item{data}{data frame}
\item{weights}{optional vector of weights for variables in \code{data}}
\item{linkage}{agglomeration method used for hierarchical clustering; corresponds to parameter \code{method} of \code{\link[stats]{hclust}}}
}
\details{Distances between subjects are based on Gower's general similarity coefficient with an extension of Podani for ordinal variables, see \code{\link[FD]{gowdis}}. In the case that all variables are quantitative, Euclidean distances are used. Then a dendrogram is derived by standard hierarchical clustering (\code{\link[stats]{hclust}} with agglomeration \code{method = "ward.D2"} by default).}
\value{An object of class \code{\link[stats]{dendrogram}}}
