Hi Karuna,
    You can try vegdist() function in the vegan package. The function
computes dissimilarity indices that are useful for or popular with community
ecologists. All indices use quantitative data, although they would be named
by the corresponding binary index, but you can calculate the binary index
using an appropriate argument.
