Extract residual standard error form aov

[asanquer@virbac.fr]

Hi,

My question is certainly very simple, but I cannot find the solution.

I would like to extract the residual standard error from the result of a
simple analysis of variance performed with the function aov. In the example
below, I would like to extract the value 0.5610507.

> aov(y ~x, data=SDF)
Call:
   aov(formula = y ~ x, data = SDF)

Terms:
                        Diametre    Residuals
 Sum of Squares   229.2976    10.7024
Deg. of Freedom         1                 34

Residual standard error: 0.5610507
Estimated effects may be unbalanced

Thanks,

Annaële Sanquer
