I just uploaded a new version of fossil to the CRAN website, with a number of changes. There are some fixes in the way the spp.est() function was handling abundance data, and I’ve added a small species/locality dataset that I used for a number of new examples in the package. I’m also currently working on a new clustering method to include, but it’s still being worked on at the moment. Hopefully it’ll be in the package before too long.
Enjoy!
