I was able to diagnose the problem. The bug occurs when there is only one polygon. I never tested that scenario; sorry about that.
I haven't had time to prepare a fix, but you can work around it by defining a second zone. It shouldn't matter where the zone is, how big it is, or if any points are in it.
I'll get back to you when I have a fix ready.
Best,
Jason

Oliver,
Thanks for your interest in MGET. Sorry about this problem. I am travelling and cannot diagnose it immediately but should be able get back to you in a couple of days.
My first guess is that the R vegan package changed its return types. As a work around, you could try temporarily downgrading to R 2.15.x or R 2.14.x.
Best,
Jason

Greetings,
What a wonderful contribution! I have just recently come across your toolset and began exploring it this morning. I was hoping to quickly implement the "Calculate
Species Diversity Index for Polygons" but for some reason I get the following error when the script attempts to write the result back into the polygon shapefile: AttributeError: 'float' object has no attribute 'has_key'. The full message from ArcGIS dialogue
box is pasted below.
Please find attached the sample data I was using: any insight would be gratefully appreciated.
Running environment: Windows 7 Professional, ArcGIS 10.1 SP1, Python 2.7, R win-library 2.14
Kind Regards,
Olivier
