Hello,
my name is Carsten. This ist my first post to R-help mailing list.
I estimate densities with the function "density" out of the package
"stats".
A simplified example:
#generation of test data
n=10
z = rnorm(n)
#density estimation
f=density(z,kernel="epanechnikov",n=n)
#evaluation
print(f$y[5])
Here I can only evaluate the estimation at given points. These points
are determined by the parameter n. By default they are equidistant
distributed on the interesting interval.
But I need to evaluate the estimation (the estimated densitiy function)
at manually specified points. For example I want to compute f(z[i]).
This means I am interested in the estimated density at a the observation
z[i].
Does anyone know how I can compute this? I think this is an ordinary
task so I would be surprised if R can not manage this. But even after a
long search I have found nothing.
Thanks in advance
Carsten Harlaß
