I am trying to set up a loop for sampling different rasters with a bunch of pointfiles within a bigger python script. The python version of "extract-multivalues-to-points" does not work, and I couldn't figure out how to pass my loop arguments onto geospatial modeling environment (GME), I planned to use R (and I want to do some batch calculations afterwards with the results anyway), but I can't get it working. I try to call it via rpy2, but when running the tests, if rpy2 is correctly installed, I always get an error, that R is not in the Path. I guess the reason is, that rpy2 is written for an older R version, and the directory structure was different then, but I have no idea how I could try to adjust this, unfortunately I am not very experienced in general commandline-scripting what makes it harder to understand the error...I use python2.6, arcGIS10 and R.2.14.1 on a windows7 machine. If someone has any idea, or a workaround, it would be awesome!! Cheers, Jutta here is the test I try to run (from the rpy2 website): import os import sys import rpy2.tests import unittest tr = unittest.TextTestRunner(verbosity = 1) suite = rpy2.tests.suite() tr.run(suite) here is the script that throws the error: import os, sys try: R_HOME = os.environ[r"C:\Program Files\R\R-2.14.1\bin\i386"] except KeyError: R_HOME = os.popen("Rgui.exe").readlines() if len(R_HOME) == 0: if sys.platform == 'win32': try: import win32api import win32con hkey = win32api.RegOpenKeyEx(win32con.HKEY_LOCAL_MACHINE, "Software\\R-core\\R", 0, win32con.KEY_QUERY_VALUE ) R_HOME = win32api.RegQueryValueEx(hkey, "InstallPath")[0] win32api.RegCloseKey( hkey ) except: raise RuntimeError( "Unable to determine R version from the registery." +\ "Calling the command 'R RHOME' does not return anything.\n" +\ "This might be because R.exe is nowhere in your Path.")
