R help - Mar 2002 - How to get the datapoints of an density estimation with locfit?

Hello!!!

I'm just a beginner of R. 
I work with locfit to get the density from an numeric vector. It looks good when
I plot the graph, but I need the output data of locfit.
For example I need somthing like that (only integer values for the input):
numeric vector (input of locfit)  	density (output of locfit) 
1				0.05....
2				0.04..
3				0.01
...

Thank you for your help and your time.

Hello,

i'm not sure but try
results <- locfit(....)
after that you can have a look at the saved things with
names(results)

As far as I know, locfit does not store its estimates.  You have to use
the fitted.values() function.  So, something like:

library(locfit)
x <- rnorm(200)
f <- locfit( ~ x)
fhat <- fitted.values(f)
cbind(x, fhat)

I think that will give you what you want.
