The package 'cluster' has a function daisy() that allows to work with combinations of "all" kinds of variables. Note that I think you mistyped "quantitative" where you meant "qualitative".

Hi all, I want to conduct a cluster analysis with quantitative variables. More precisely, it concerns binary and non-ordered categorical variables. For such data, various similarity measures have been proposed, such as the Jaccard index or the simple matching index. So, is there a package such as mva or multiv in the case of quantitative variables? Could you indicate me reviews, papers or technical reports dealing with this problem?
