## Plot an equiv.clust Object

### Description

Plots a hierarchical clustering of node positions as generated by `equiv.clust`.

### Usage

    plot.equiv.clust(x, labels=NULL, ...)

### Arguments

`x` | An `equiv.clust` object
`labels` | A vector of vertex labels
`...` | Additional arguments to `plot.hclust`

### Details

`plot.equiv.clust` is actually a front-end to `plot.hclust`; see the latter for more additional documentation.

### Value

None.
