Hi Krissey, I think what you need is the object (probably a matrix or data frame) that contains the present/absent codes for all of the species recorded. It looks to me as though the venn.diagram function wants a list with the indices of "present" codes for each set, and calculates the intersections from that. If you have that list, you can work backward to generate the initial present/absent matrix for all species. You will have to know the order of the rows in the initial matrix to identify which species is which.
