python-rpy has 2 reverse dependencies. It looks like the best thing to
do is to port piuparts-report charting [1] to rpy2. I tried a quick
hail mary pass at directly replacing rpy with rpy2.rpy_classic - any
command I try parses like this:
$ python
Python 2.7.3 (default, Mar 4 2013, 14:57:34)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from rpy2.rpy_classic import *
>>> r('t <- (read.table("counts.txt",sep=",",header=1,row.names=1))')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/dist-packages/rpy2/rpy_classic.py", line
283, in __call__
return self.eval(self.parse(text=s))

res = self.__getitem__(name)
File "/usr/lib/python2.7/dist-packages/rpy2/rpy_classic.py", line
279, in __getitem__
res = rpy2py(res)
File "/usr/lib/python2.7/dist-packages/rpy2/rpy_classic.py", line
186, in rpy2py
raise ValueError("Invalid default mode.")
ValueError: Invalid default mode.
Can you provide some pointers to an R neophyte on how to proceed?
