R help - Sep 2005 - confidence variability bands for kernel estimators

I'm using nonparametric regression (packeges ksmooth and ks). My question:
is there any way to compute confidence bands (or variability bands) with R.
Confidence bands for functions are intervals [CLO(x);CUP(x)] such that with
probability 1-alpha the true curve is covered by the band [CLO(x);CUP(x)].

Thanks very much for any help you can offer.

The `sm' package has functionality to produce pointwise band.  The
`locfit'
package can produce simultaneous band.  Both are support software for books,
where you'll find more detail.
