upset attributes

[dgcovell]

From the UpSetR issues listed I find that others are seeking to determine the member ids within the
numbers listed at the top of each bar of the 'Intersection Size' plot. Further blogging finds that this is
both complex and not straight-forward (see https://krassowski.github.io/complex-upset/articles/Examples_R.html#0-2-region-selection-modes).

Failing to find a simple answer, I created tmp_upset <- upset(... and parsed the fields in
tmp_upset$New_data (which in my case is 420x7) to build the sets of intersecting row.names(tmp_upset$New_data) for each of the 7 fields. From these results I can tediously
reconstruct the members associated with each of the bars in the plot of Intersection Size.

Before I abandon further hope, I would ask the pros whether somewhere buried in attributes(tmp_upset)
or names(tmp_upset$Main_bar) I might find an easier solution,
Attributes 'Main_bar' and 'heights' or 'name' looked promising, but did not yield results that I could uncover.

Any help would be appreciated.

David
