Hello there,
I am presently using the locfit package in "R" and would appreciate some help here. Could anyone tell me tell me how I can obtain the various components (x and y values)of the density estimation after using the "R" command "locfit"? For example, with the command "fhat<-density(somename)" I can obtain the x and y values by simply calling "fhat$x" and "fhat$y". This doesn't seems to work with the "locfit" command.
Thank you in advance.
Regards,

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,
