Hi Darren,
Just installed manageR (0.6.10) on Windows Vista.
Qgis 1.0.2-Kore installed via standalone installer, R version is 2.9.
ManageR installed via the python plugin installer, following Carson's
guide at: http://www.ftools.ca/install.html
Got a python error (below) and it looks like manageR can't find R.
This is not too surprising as I set HOME, R_USER etc via a
Renviron.site file.
So R is not in the registry and no environment variables are set.
How do I show manageR where the R.exe file is??
In this case you'll have to set an environment variable I think.
The error that you posted comes up when the following fails:
try:
R_HOME = os.environ["R_HOME"]
except KeyError:
R_HOME = os.popen("R RHOME").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.")
So obviously if R isn't in the registry, and there is no R_HOME
environment variable, Rpy (which is what manageR uses to talk to R)
won't be able to find R. Essentially, you just need to specify the
R_HOME environment variable as your R install path.
The other option is to add something like:
import os
os.environ['R_HOME'] = "R/install/path"
to line 20 of either __init__.py or manageRDialog.py in the manageR
plugin directory.
Hope that helps,
Carson
