On the ?locfit help page it says:
An object with class '"locfit"'. A standard set of methods for
printing, ploting, etc. these objects is provided.
This implies that there should be a fitted.locfit method. And, indeed,
there is:
data(ethanol)
x <- ethanol$E
fit <- locfit(~ x)
plot(x[order(x)], fitted(fit)[order(x)], type = "n")
HTH,
