Description Usage Arguments Value See Also Examples

Compare two sets of signatures, stored in numerical data frames W1 and W2, by computing the column-wise cosine distance

1	compare_sets(in_df_small, in_df_big, in_distance = cosineDist)

`in_df_small, in_df_big`	Numerical data frames `W1` and `W2`, ideally the bigger one first, both with `n` rows and `l1` and `l2` columns, `n` being the number of features and `l1` and `l2` being the respective numbers of signatures of `W1` and `W2`
`in_distance`	A function which computes the distance measure, default is `cosineDist`

A list with entries distance, hierarchy_small and hierarchy_big.

distance: A numerical data frame with the cosine distances between the columns of W1, indexing the rows, and W2, indexing the columns
hierarchy_small: A data frame carrying the information of ranked similarity between the signatures in W2 with the signatures in W1
hierarchy_big: A data frame carrying the information of ranked similarity between the signatures in W1 with the signatures in W2
