Hello, 

I would like to create density distribution plots for a given environmental variable to compare values of the variable in different locations (presence/absence locations). The point shapefile I am using has the following columns: LON, LAT, Category (0 or 1), Chlorophyll

Everything has the format it should have. However, I received the following error which I do not understand:

Executing: RExploratoryPlotsDensityHistogramForArcGISField RW_SW_oct 0_5_chl_10 # category # # # 1000 3000 3000 10 white
