[R] Confidence intervals for beta distribution

[Eleni Rapsomaniki]

Dear R users,

Sorry if this is too trivial. Is there a way to get confidence intervals for a
beta distribution? e.g. Is this wrong for calculating the 2.5% lower CI for a
distribution with parameters 13.2 and 691?

qbeta(0.025, 13.2, 691)

Also, is there a way to get CI for a dirichlet distribution?

Many Thanks in advance,
Eleni Rapsomaniki
