[IPython-user] rpy.princomp missing when using ipython

[Stefan Vey]

Hi!
I'm new to python and have a question/problem.
I am using IPython 0.8.1 (installed from repositories) on Kubuntu 7.10. When I 
import rpy in ipython, I cannot access the rpy.princomp function to perform 
principal component analyses. And why do I have to use "rpy." instead of "r." 
which works in plain python console? This problem only exists when I use 
Ipython, everything is fine in the standard python shell, so I guess the 
problem is in Ipython.
hoping for help
Stefan
