# Small example in which the interior-point method (implemented in
# MOSEK) yields negative mixture weights. These mixture weights are
# automatically set to zero and the weights are re-normalized. The
# EM algorithm does not suffer from this problem.

fit.em  <- ash(betahat,sebeta,mixcompdist = "normal",optmethod = "mixEM")
fit.mixsqp  <- ash(betahat,sebeta,mixcompdist = "normal",optmethod = "mixSQP")
fit.ip  <- ash(betahat,sebeta,mixcompdist = "normal",optmethod = "mixIP")

The third one does not work.
