python - rpy2 import is not working -


When I try to import rpy2, I get an error. Here is the code and error 

  & gt; & Gt; & Gt; Import Traceback (Most Recent Call Final): File "C: \ PF \ WinPython-64bit-3.3.3.3 \ python-3.3.3.amd64 \ lib \ site-packages \ IPython \ core \ interactiveshell.py", line 2828 In the file, "ipython-input-148-c258a0f70d44" gt; Row 1, & lt; modules & gt; Import pandas.rpy.common file in runcode ajl (code_obj, self.user_global_ns, self.user_ns) file " C: \ PF \ WinPython-64bit-3.3.3.3 \ python-3.3.3.amd64 \ lib \ site-packages \ pandas \ rpy \ common.py ", line 14, in & lt; modules & gt; Rpy2.robjects .packages Import Import Import Import: A module name 'rpy2'

What could be the problem? I Python Version 3.3.3 and PANDAS Version 0.13.1

Edit

Tried to install rpy2 separately

  1. I get an error using python setup.py install which is not the module popen3 in OS .

  2. Running the site of Christophe Gohalke properly installing XE (rpy2-2.3.9.win32-py3.3.exe) directly. But if I try to do import pandas.rpy.common com then I get the following error (rpy2.rinterface._rinterface Import * to with DLL loading Problem) : 

      traceback (most recent call final): File "C: \ PF \ WinPython-64bit-3.3.3.3 \ python-3.3.3.amd64 \ Lib \ site-packages \ IPython \ core \ interactiveshell.py ", edit run_code exec (code_obj, self.user_global_ns, self.user_ns) file" ipython-input-10-63ebebefea80 ">, line 1, In & lt; Module & gt; Import pandas.rpy.

edit

resolve it at the end. It seems that adding R_HOME and R_USER environment variables is a trick. RPy2 is a separate project from Panda, so you have to set it apart. You should be able to do pip installation rpy2 , then restart the python and try again.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
