Summary: rpy2 bug in qGIS - Home Range pluging not working
Initial Comment:
I am not a developer so sorry if this doesn't have everything you need. Please
ask and I will be happy to supply additional information.
I am trying to run the Home Range plugin from within qGIS. This plugin calls
the package 'adehabitat' from within R. Adehabitat loads and runs fine from
within R, as does ade4 and gdal (both required by adehabitat). I contacted
Anna Ghisla, the developer of the plugin, and she suggested some tests and now
thinks I have a bug with RPy2. I tried running Home Range from the GUI of
qGIS, and also from the Python console (as Anna suggested). Both produced
errors (see below). I have the following system/software:
Dell Precision 390 running Windows XP sp 3
R2.9.1 with adehabitat, ade4, and rgdal
from OSGeo4W I have installed:
qGIS 1.0.2-2
Python 2.5.2-1
Python-numpy
Python-qGIS
Python-rpy2
Python-Win32
When I try to run adehabitat from the Python console within qGIS I get the
following error:
>>> import rpy2.robjects as robjects
>>> robjects.r.require("adehabitat")
RRuntimeError: Error: package 'ade4' could not be loaded
>>> robjects.r.require("ade4")
[1] FALSE
Running the Home Range plugin from the qGIS GUI gets the following error:
An error has occured while executing Python code:

I understand this has been a problem on previous versions but was supposed to
have been fixed (ticket at: https://trac.faunalia.it/animove/ticket/7)
Thanks for looking into this. Please let me know if you need additional
information.
