R help - Apr 2011 - Difference in mixture normals and one density

Hello,
I am trying to find out if R can do the following:

I have a mixture of normals say f = 0.2*Normal(2, 5) + 0.8*Normal(3,2)
How do I find the difference in the densities at any particular point of f
and at Normal(2,5)?

-- 
Thanks,
Jim.

Is something like this what you're looking for?

R> library(nor1mix)
R> nmix2 <- norMix(c(2, 3), sig2=c(25, 4), w=c(.2, .8))
R> dnorMix(1, nmix2) - dnorm(1, 2, 5)
