rpy2

I am trying, so far unsuccessfully, at installing the rpy2 for python on my Mac OSX. I have tried Macports and DarwinPorts but have had no luck with import rpy2 within the python shell environment. I don't know much about programming in Mac and I am a wiz at installing modules on a Windoze based system, but for the life of me cannot do a simple port on my Mac at home. What I am after, if someone would be so kind, are "dumbed down" instructions for a successful install of rpy2 for Mac OSX Snow Leopard. Hopefully someone here has done this successfully and can outline the process they took? At

I have a numpy 2D array self.sub and i want to use it in rpy2 kmeans. k = robjects.r.kmeans(self.sub,2,20) i always get the following error: valueError: nothing can be done for the type at the moment! what can i do? From the rpy2 docs , R matrices are just vectors with their dim attribute set. So for a numpy two-dimensional array x import rpy2.robjects as robj nr, nc = x.shape xvec = robj.FloatVector(x.transpose().reshape((x.size)) xr = robj.r.matrix(xvec, nrow=nr, ncol=nc) You have to transpose the numpy array because R fills matrices by columns. Edit: Actually, you could just set byrow=True

I'm using Rpy2 on windows 7 64 and having trouble loading a package: in R: using(mi) in python: from rpy2.robjects.packages import importr mi=importr('mi') --------------------------------------------------------------------------- RRuntimeError Traceback (most recent call last) <ipython-input-30-2d393a6df544> in <module>() ----> 1 mi=importr('mi') C:\Anaconda\lib\site-packages\rpy2\robjects\packages.pyc in importr(name, lib_loc, robject_translations, signature_translation, suppress_messages, on_conflict, data) 397 if _package_has_namespace(rname, 398 _system_file(package = rname)): --> 399

I am trying to calculate and generate plots using multiprocessing. On Linux the code below runs correctly, however on the Mac (ML) it doesn't, giving the error below: import multiprocessing import matplotlib.pyplot as plt import numpy as np import rpy2.robjects as robjects def main(): pool = multiprocessing.Pool() num_figs = 2 # generate some random numbers input = zip(np.random.randint(10,1000,num_figs), range(num_figs)) pool.map(plot, input) def plot(args): num, i = args fig = plt.figure() data = np.random.randn(num).cumsum() plt.plot(data) main() The Rpy2 is rpy2==2.3.1 and R is 2.13.2 (I

I get an error when I try to import rpy2. Here is the code and error. >>> import pandas.rpy.common Traceback (most recent call last): File "C:\PF\WinPython-64bit-3.3.3.3\python-3.3.3.amd64\lib\site-packages\IPython\core\interactiveshell.py", line 2828, in run_code exec(code_obj, self.user_global_ns, self.user_ns) File "<ipython-input-148-c258a0f70d44>", line 1, in <module> import pandas.rpy.common File "C:\PF\WinPython-64bit-3.3.3.3\python-3.3.3.amd64\lib\site-packages\pandas\rpy\common.py", line 14, in <module> from rpy2.robjects.packages import importr ImportError: No module named 'rpy2'

I've been having a real issue trying to make Rpy2 play nice with my R install. I first tried installing the rpy2 MSI package, and this didn't appear to work. When I ran the recommended tests, it was giving me an error saying that it couldn't find the R.dll, because the new R installs (post 2.11) install the DLLs into an i386 folder, where rpy2 can't find them because its looking in the bin folder instead of the bin/i386 folder. Then I tried to build the install from scratch myself using the command line tools (distutils) included with python. This didn't work, because setup.py claimed to be

I have tried every install method I can think of to install RPy2 on our debian server and I get the same message regardless. I have installed and used it successfully on my mac. Is there something I may be missing? start Processing rpy2 Running setup.py -q bdist_egg --dist-dir /opt/rpy2/egg-dist-tmp-oft2ko returned an empty string. returned an empty string.
