> I mange to import rpy to python and I can use R functions, but not plot.

> x = range(0, 10)
> y = [ 2*i for i in x ]
> r.plot_default(x, y)
> r.plot(x,y)
>
> As well, I cannot save plot to file, as can be seen from this example:

> my_y = [1.65, 26.5, -5.93, 7.96]
> ls_fit = r.lsfit(my_x,my_y)
> gradient = ls_fit['coefficients']['X']
> yintercept = ls_fit['coefficients']['Intercept']
> r.png("scatter_regression.png", width=400, height=350)
> r.plot(x=my_x, y=my_y, xlab="x", ylab="y", xlim=(0,7), ylim=(-16,27),
> main="Exmple Scttr w/regression")
> r.abline(a=yintercept, b=gradient, col="red")

> The .png file is created but it is empty.
