[R-sig-Geo] Load R sp vector layers in QGIS

[Agustin Lobo]

Carson,

This is geting close to my dreams, but
when I try to load the plugin, I get:
An error has occured while executing Python code:

Traceback (most recent call last):
  File "", line 1, in
  File "/home/alobo/.qgis//python/plugins/loadRlayer/loadRlayer.py", 
line 58, in initGui
   self.fileBar = self.iface.fileToolBar()
AttributeError: fileToolBar


(using QGIS 0.10 on ubuntu hardy from binaries, trying to build another 
version from svn)
