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
