I am having problems with rp2.rpy_classic with conversions. If I do:
$ python
Python 2.5.2 (r252:60911, Aug 20 2008, 17:14:32)
[GCC 4.1.2 20070115 (prerelease) (SUSE Linux)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from rpy2.rpy_classic import *
>>> set_default_mode(NO_CONVERSION)
>>> x = r.seq(1, 3, by=0.5)
>>> print x
<rpy2.rpy_classic.Robj object at 0x2ba5a898c710>
>>>
>>> set_default_mode(BASIC_CONVERSION)
>>> x = r.seq(1, 3, by=0.5)
Traceback (most recent call last):

File
"/opt/freeware/Python/Python-2.5.2/lib/python2.5/site-packages/rpy2/rpy_
classic.py", line 215, in __call__
res = rpy2py(res)
File
"/opt/freeware/Python/Python-2.5.2/lib/python2.5/site-packages/rpy2/rpy_
classic.py", line 174, in rpy2py
res = rpy2py_basic(obj)
File
"/opt/freeware/Python/Python-2.5.2/lib/python2.5/site-packages/rpy2/rpy_
classic.py", line 154, in rpy2py_basic
if obj.typeof() in [ri.INTSXP, ri.REALSXP, ri.CPLXSXP,
TypeError: 'int' object is not callable
>>>
So with no conversion I can use seq(1,3), but with basic conversion I
can't seem to. I am using python 2.5.2, R-2.8.0 on Suse x86_64. Any
suggestions as to why the conversion doesn't work?
I have tried other examples, like
$ python
Python 2.5.2 (r252:60911, Aug 20 2008, 17:14:32)
[GCC 4.1.2 20070115 (prerelease) (SUSE Linux)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import rpy2.robjects as robjects
>>> x = robjects.r.seq(1, 10)
>>> print x
[1] 1 2 3 4 5 6 7 8 9 10
>>> x.r[-1]
2:10
>>>
and they work fine.
I did the test of the install and got results like this:
$ python
Python 2.5.2 (r252:60911, Aug 20 2008, 17:14:32)
