Hi,

The diversity index is exactly what I need, but, as per the title, I'm having a problem executing it. Specifically, the tool seems to encounter a problem when bringing the results back to ArcMap (10.3.1). The full error log is quoted at the end of the email.

A similar (identical?) issue was raised in 2013. Following on from the troubleshooting there, I created a second random zone of interest polygon. This, unfortunately, did not alleviate the situation.

The other solution mooted there was that maybe it's something to do with R? I've not tried downgrading our version of R (3.1.1) just yet, as I do not have admin rights to the machine. As such, I'd rather have a confirmation that this is the case before dragging IT into the situation!

I've attached the sample data I was testing on, if that is of any use.

Many thanks for any help,
Euan Forsyth
