[R] R function which finds confidence interval for binomial variance

[Robert A. LaBudde]

I need to construct confidence intervals for the binomial variance. 
This is the usual estimate

	v = x*(n-x)/n

or its unbiased counterpart

	v' = x*(n-x)/(n-1)

where x = binomial number of successes observed in n Bernoulli trials 
from proportion p.

The usual X^2 method for variance confidence intervals will not work, 
because of the strong non-normal character of the sampling 
distribution for v (or v').

Does anyone know of an R package with R function that computes a 
reasonable confidence interval for v or v'?

Thanks.
