The "betareg" package provides a function betamix() for finite mixture
models of beta regressions (which may be beta distributions if no
regressors are included). Maybe that is useful for you? It is described in
the vignette("betareg-ext", package = "betareg").

Not in betamix(). Parameters are estimated freely.
