[R] problem with optim and integrate

Dear all, I want to min "integrate( (p1*dnorm+p2*dnorm+p3*dnorm)^(1.3))" for p, mu, and sigma. So, I have to estimate 8 parameters(p3=1-p1-p2). Sometimes I got some results, but it was bad, sometimes, I got this warning-"Error in integrate(numint, lower = -Inf, upper = Inf) : non-finite functio
