[R] function for linear regression with White std. errors

[Brian Quinif]

I would like to know if there is a function that will run a linear
regression and report the White (heteroscedasticity consistent) std.
errors.

I've found the hccm() function in the car library, but that just gives
me the White covariance matrix.  I'd like to be able to see the White
std. errors without having to do much more work, if possible.

Thanks,

Brian
