[IPython-dev] Rmagic under Debian Squeeze problem

[Javier Martínez-López]

*Dear all,

I need to run R code with the IPython notebook in my Debian squeeze desktop
computer. **I can apparently load the rmagic extension but when I try to
run R code I get the following error message:

*AttributeError                            Traceback (most recent call last)
