daisy() in recommended package 'cluster' can generate dissimilarities
for ordinal data using Gower's general (dis)similarity coefficient for
mixed data. It returns an object that inherits from dist so it can be
used in clustering tools that accept dist objects. Check out the options
in the cluster package itself, but also note you can use hclust in base
R.

For more information, see if the details on the Cluster Task View help:
