Hi,
I have estimated Niche overlap from ENM Tools software for 3 species by 1:1 pair, such as
A:B, B:C, and A:C
However I could not find the overlap between 3, A:B:C
is there a way to do this. I need this a value to plot a venn diagram, where it asks for intersect of 3.
or please suggest me to present this in other way.
many thanks.
I tried similar things in Venn diagram using the venn package in R, but later I realized it's much better to do it in power point! Seriously! You may try that just add your data manually and present them graphically! My r output looks very messy and untidy, and I even talked to few amazing R expert thy also suggested me the r code for this particular task is not really a great one! :)
Hypervolume package in R. allows to show them graphically. However, as in your case, sorensen overlaps are calculated by pairs.

Hi. Have you figure out this problem. I find EcoSimR do not meet our requirements., e.g. can not calculate Schoener’s D of 3 species. Steven L. Van Wilgenburg Madan K. Suwal
Hi Peng Zhang , I guess it may be someowha dependent on your data structure, but you could also look at the niche.overlap function in the phyloclim package.
