Dear all,

I have a discrete distribution showing how age is distributed across a
population using a certain set of bands:

Age <- matrix(c(74045062, 71978405, 122718362, 40489415), ncol=1,
dimnames=list(c("<18", "18-34", "35-64", "65+"),c()))
Age_dist <- Age/sum(Age)

For example I know that 23.94% of all people are between 0-18 years, 23.28%
between 18-34 years and so forth.

I would like to find a continuous approximation of this discrete
distribution in order to estimate the probability that a person is for
example 16 years old.

Is there some automatic way in R through which this can be done? I tried a
Kernel density estimation of the histogram but this does not seem to
provide what I'm looking for.

Thanks very much for your help,

Michael
