Hello again, apologies for the frequent postings, but as I'm finding some stumbling blocks, I'm trying to determine if it's an error on my part or my installation.
If I try to run the RS4_Auto_Type example from the rpy2 documentation, I get:
In [28]: %cpaste
Pasting code; enter '--' alone on the line to stop.
:from rpy2.robjects.packages import importr
:stats4 = importr('stats4')
:from rpy2.robjects.methods import RS4, RS4Auto_Type
:
:class MLE(RS4):
: __metaclass__ = RS4Auto_Type
: __rname__ = 'mle'
: __rpackagename__ = 'stats4'
:--
Warning message:
In function (f, where, classes = character(), inherited = FALSE, :
non-generic function 'Biobase' given to findMethods()
[...]
LookupError: The object has no such attribute.
The culprit is at line 191 in robjects/methods.py:
for name, meth in itertools.izip(all_methods.do_slot("names"), all_methods):
Further debugging has shown that all_methods is empty.
Should I file a bug, or is it likely a local install problem?
