A setmap showing which original variables make up the sets at a
certain depth
Arguments
original_variables
Character vector of names for the original
variables that were paired (typically `pairmi_result$original.variables`).
sets
A data frame returned by [pairmi()] describing the sets. Must
contain the columns required by `setmapmi()` (e.g., identifiers for sets
and their constituent variables).
n_elements
Integer scalar giving the set size (depth) to visualize
(e.g., `2` for pairs, `3` for triplets). Must be >= 1 and present in
`sets`.
