There was a typo error in my code below. See the inserted correction.

You guys are really good.
Thanks.

f is a list of things, including x values where the density is computed,
and y values for the density there. So you could do it by linear
interpolation using approx or approxfun. For example
> b <- runif(1000,
Hi, guys,
I'm using kernel "density" estimation. But how can I return to a density
estimation for a fixed point?
For example,
b<-runif(1000,0,1)
f<-density(b)
How can I get the value of density(b) at b=0.5?
Your help is extremely appreciated. Thanks.
Jay
