...Could not find function "Tool_exec"

[JoshFlad]

Hello GeoNet Community

I'm trying to run a script to derive individual tree crowns from lidar datasets. The script "recipe" is provided by the PA Department of Conservation & Natural Resources, Bureau of Forestry. I am new to R and the ArcGIS Pro and the ArcGIS R integration process however I've followed the instructions carefully. 

The script runs and R produces graphics resembling the desired outputs but then returns and error stating - could not find function "Tool_exec". I'm not sure how this is possible. I'm using Microsoft Open 3.5.3 and arcgisbinding package 1.0.1.239. 

Any advice would be greatly appreciated!  Thanks

I am also getting the same issue. Did your problem get solved.

Hey Josh, do you have more context that you can provide? There is not much that we can work off of. But one thing that I am aware of is that the function must be called `tool_exec()` and not Tool_exec(). 

Capitalization is really important here.
