[IPython-dev] R inside IPython (notebook, qtconsole or regular terminal)

Hi folks,

thanks to Jonathan Taylor (and those who contributed with review),
we've just merged this PR:

https://github.com/ipython/ipython/pull/1780

that lets you seamlessly use R from any IPython client.  This is what
it looks like in the notebook:

but you can equally use it from a terminal:

In [5]: X = np.array([0,1,2,3,4])

In [6]: Y = np.array([3,5,4,6,7])

In [7]: %load_ext rmagic

In [8]: %%R -i X,Y -o XYcoef
   ...: XYlm = lm(Y~X)
   ...: XYcoef = coef(XYlm)
   ...: print(summary(XYlm))
   ...:

Call:
lm(formula = Y ~ X)

Residuals:
   1    2    3    4    5
-0.2  0.9 -1.0  0.1  0.2

Coefficients:
            Estimate Std. Error t value Pr(>|t|)
(Intercept)   3.2000     0.6164   5.191   0.0139 *
X             0.9000     0.2517   3.576   0.0374 *
---
Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1

Residual standard error: 0.7958 on 3 degrees of freedom
Multiple R-squared:  0.81,	Adjusted R-squared: 0.7467
F-statistic: 12.79 on 1 and 3 DF,  p-value: 0.03739

In [9]: XYcoef
Out[9]: array([ 3.2,  0.9])


We also have an octave one coming
(https://github.com/ipython/ipython/pull/1849) by Stefan, as well as
magics to access the shell and save files in the notebook server
(https://github.com/ipython/ipython/pull/1855).

I figured this group would particularly like the R one.  Many thanks
to Jonathan for the patient work during the fairly detailed review we
had prior to merging!

Cheers,

f
