One method I know of uses the bootstrap, and is described in "An
Introduction to the Bootstrap" by B. Efron and R. Tibshirani, 1993, Chapman
and Hall. And the contributed package "bootstrap" contains code and data for
this book, so I presume (without actually having looked at the package :-)
that what you need is there.

Subject: [R] test for bimodality
Dear R users,
I'm looking for a test of bimodality in order to make some decisions about
how to procede with an analysis algorithm. I have not come across any such
tests in my readings and discussions apart from the Rao which appears to be
applicable to cyclic data.
The data I'm interested in characterizing as uni- or bimodal are frequency
x amplitude spectra of consonant speech sounds, where the spectrum, a line
graph is treated as a frequency distribution.
Thanks in advance for your input.
