[R] Density estimates in modelling framework

[hadley wickham]

Hi all,

Do any packages implement density estimation in a modelling framework?
 I want to be able to do something like:

dmodel <- density(~ a + b, data = mydata)
predict(dmodel, newdata)

This isn't how sm or KernSmooth or base density estimation works.  Are
there other packages that do density estimation?  Or is there some
reason that this is a bad idea.
