[Qgis-user] Qgis/Rpy spqr plugin

[Sampson, David]

Hey folks.

I saw this plugin and became quite interested.

http://www.maths.lancs.ac.uk/~rowlings/Software/Spqr/

I followed the instructions for insatalling

I receive the following error when I start up Qgis:

Couldn't load plugin "spqr" from ['C:/Documents and Settings/dsampson/.qgis//python/plugins', 'C:/Program Files/Quantum GIS/./python', 'C:/Program Files/Quantum GIS/./python/plugins', 'C:\Python25\Lib\site-packages\gmt-20050124', 'C:\Python25\Lib\xml', 'C:\Program Files\Quantum GIS\python25.zip', 'C:\Python25\Lib', 'C:\Python25\DLLs', 'C:\Python25\Lib\lib-tk', 'C:\Program Files\Quantum GIS', 'C:\Python25', 'C:\Python25\lib\site-packages', 'C:\Python25\lib\site-packages\win32', 'C:\Python25\lib\site-packages\win32\lib', 'C:\Python25\lib\site-packages\Pythonwin']

Traceback (most recent call last):

 File "C:\Python25\Lib\site-packages\rpy.py", line 286, in __init__
  _rpy.r_init(HAS_NUMERIC);
RuntimeError: Only one R object may be instantiated per session




Details:
------------
Qgis version 0.10.0
Python: 2.5
R: 2.70
Rpy: rpy-1.0.3-R-2.7.0-win32-py2.5




Any ideas?... I am a beginner in Python, have used QGIS for a while and willing to tinker if I know where to start.


Cheers
