[IPython-dev] use of InteractiveShell and R magic

Thanks, that seems to work in a separate python process rather than the
ipython process:

~/workbook (metadata*) $ python -c "import
IPython.frontend.terminal.interactiveshell as IS; shell =
IS.TerminalInteractiveShell(); shell.run_cell('%load_ext rmagic');
shell.run_cell('%R X=rnorm(20); print(X)')"
 [1]  0.2125483  0.1030451 -1.4036373 -0.5617847 -0.7571675 -0.3985085

~/workbook (metadata*) $ python -c "import
IPython.frontend.terminal.interactiveshell as IS; shell =
IS.InteractiveShell(); shell.run_cell('%load_ext rmagic');
shell.run_cell('%R X=rnorm(20); print(X)')"
 [1]  0.44037484  1.31372601 -0.37253955  2.21955270 -0.07886852 -0.09022193
 [7]  0.38464850 -0.41004855  1.62648041 -0.13687832  0.91537699 -2.70125217
[13]  1.49125226  0.11580012 -0.64993087  2.49367657  0.01447792  0.57408249
[19] -0.80559871 -0.76346964

So, for interactively running this in ipython I should expect to see this
load_ext failure?

Thanks,

Jonathan
