<h3>Details</h3>


<p>Most of factor attributes are not disjunctive. For example, a plant can be usually
pollinated by insects but sometimes self-pollination can occured.

<pre>
data(plantTraits)

## Calculation of a dissimilarity matrix
library(cluster)
dai.b &lt;- daisy(plantTraits,
               type = list(ordratio = 4:11, symm = 12:13, asymm = 14:31))

## Hierarchical classification
agn.trts &lt;- agnes(dai.b, method="ward")
plot(agn.trts, which.plots = 2, cex= 0.6)
plot(agn.trts, which.plots = 1)
cutree6 &lt;- cutree(agn.trts, k=6)
cutree6

## Principal Coordinate Analysis
cmdsdai.b &lt;- cmdscale(dai.b, k=6)
plot(cmdsdai.b[, 1:2], asp = 1, col = cutree6)
