coefficient of partial determination...partial r square [ redux]

If I'm not mistaken, partial R-squared is the R^2 of the quantities plotted
in a partial residual plot, so you can base the computation on that.  Prof.
Fox's `car' package on CRAN has a function for creating those plots, but you
need to figure out the way to extract the quantities being plotted.

[In any case, the basic tools for doing such computations are all in R, and
it shouldn't be hard at all to cook up such a thing, starting from the
formula.  Writing a function that works on any conceivable models that can
be fitted with lm() would be a bit more challenging, but I doubt you need
that.]

After the deafening silence from my last post (which likely caused
shudders of disgust in statistics departments on the six continents)
I'll reformulate:

Is there a function that will return the coefficients of partial
determination for the independent variables in a lm (or glm). For y =
x1 + x2....xn can I use R to extract the partial rsq for x1 to n?

I am, and remain, with Admiration, etc. etc., at your Bidding,
