I have created a Python script which calls an R script and then reads the output back into Python. I can run this tool in ArcGIS Desktop (10.2.1) and it works fine. When I publish as a geoprocessing service it fails once it reaches the R script. I have checked the file paths and they are fine. Is it even possible to call external scripts from a geoprocessing service? Here is my code.
import sys, os, arcpy
arcpy.AddMessage("Loaded Python Imports...")
try:
#User Input
lat = arcpy.GetParameterAsText(0)
long = arcpy.GetParameterAsText(1)
arcpy.AddMessage("LAT: " + "".join(lat))
arcpy.AddMessage("LONG: " + "".join(long))
#Create R Command
rScript = "test.R"
args = " ".join([lat, long])
RCMD = "R --slave --vanilla --args "
cmd = RCMD + args + " < " + rScript
#Execute
os.system(cmd)
#Render the Results
output = open("FILE PATH")
finalNumber = output.read()
print("The output is: " + " ".join(finalNumber))
arcpy.AddMessage("The output is: " + " ".join(finalNumber))
output.close()
#Delete Text File
os.remove("FILE PATH")
except Exception as e:
print e.message
arcpy.AddError(e.message)
Rscript test.R arg1 arg2 arg3
instead? Just in case you weren't aware of that option, here's a simple example of what that looks like in practice. – Josh O'Brien Mar 6 '14 at 0:44
