[R] rstandard does not produce standardized residuals

[Ulrich Halekoh]

Dear all,


the application of the function rstandard() in the base package
 to a glm object does not produce  residuals standardized to 
have variance one:

the reason is that the deviance residuals are  divided
by the dispersion estimate and not by the
square root of the estimate for the dispersion.

Should the function not be changed to produce residuals
with a variance about 1?
