[R] cauculating dissimilarities in R

Dear All,
I’ve got a statistical question on calculating dissimilarities in R.
I want to calculate the different types of dissimilarities on the ‘flower’ dataset found in the package ‘cluster’. Flower is a data frame with 18 observations on 8 variables. Variable 1 and 2 are binary, variable 3 is asymmetric binary, variable 4 is nominal, variable 5 and 6 are ordered and variable 7 and 8 are interval scaled.

Commands to load the dataset in R.

What are the different types of dissimilarities that can be calculated on such a dataset?
Do I need to group the types of variables first i.e. all binary together then run the calculation? Do I use dissimilarity indices such as Jaccard or should it be classification function such as ‘daisy’ which should be used?

Many thanks,
