Dan, I'm not familiar with 3D or numpy, so I don't know if they are capable of the same raster calculation. Something to look into, thanks!

I would like to create a tool to use in Model Builder with other tools to automate a series of processes that involves creating a raster in ArcGIS then running a script in R and adding the results back into ArcGIS. See my original post for the exact function I am using in R.

Thanks for the reply, Steve! Looking forward to when raster data is supported to be able to automate some processing.

I have an R script that uses the spatialEco package to create percent volume rasters. It works well as a stand-alone script but I would like to create a script tool in ArcGIS to use in ModelBuilder. The error I am getting seems related to the fact that the 'raster.vol' function needs to operate on a raster layer object but when I use the 'arc.open' function in my script, my raster opens as a :RasterDataset and arcgisbinding doesn't seem to have an inherited method to allow me to use the 'raster' function to convert the object to a raster layer. Any suggestions?

Thanks, Dan. Eric Krause actually had the reasoning I was looking for. I didn't realize the GA layer wasn't showing the full extent of predicted values that are seen in the raster created from it.

Thanks, Steve. I have read this before, it wasn't clear to me why the GA layer didn't show negative values. Eric Krause's answer helped.

I understood that RBF could result in values above or below, what I didn't realize is that the values shown in the GA layer weren't the full extent. Thank you. Using a different subset of my data, I didn't see the negative values when making the raster from the GA layer and so thought this was strange. But looking at my point spread between the two subsets, I see that there is a greater 'no data' area in the second subset and that must be influencing the negative raster values.

I have used the Geostatistical Analyst Wizard to interpolate point data using the radial basis function. The GA layer created has a minimum value of "0" and a maximum value of "114" which correlates to the point data values used. However, when I use the tool "GA Layer to Grid", I am getting a minimum value of "-4.04". I understand the mins and maxes for the raster aren't going to match because the values are averaged within the cell created, but how can a negative value be returned when none exist in the original point data or the GA layer?

It does work manually in ArcMap using the Make XY Event Layer tool. I have tried deleting the tool in ModelBuilder and adding it back in with no success. I'm truly stumped!

Other than the projection differences, your Make XY Event Layer code is the same as mine. Thanks, though.

Had a model built that worked about a month ago and today I can't figure out why it is getting stuck at the Make XY Layer step. Here is the Python code from the model: arcpy.MakeXYEventLayer_management(CopiedTbl_View, "Lon", "Lat", XYLayer, "GEOGCS['GCS_WGS_1984',DATUM['D_WGS_1984',SPHEROID['WGS_1984',6378137.0,298.257223563]],PRIMEM['Greenwich',0.0],UNIT['Degree',0.0174532925199433]];-400 -400 1000000000;-100000 10000;-100000 10000;8.98315284119522E-09;0.001;0.001;IsHighPrecision", "") I made sure that the table being imported from an Access database in previous steps has the Lat/Lon field in numeric format and still it doesn't work. I have attached a pic of the whole model for reference.
