[R-es] what´s wrong with this code?

Hello, I want to maximize a likelihood function expressed as an
integral that can not be symbolically evaluated. I expose my problem
in a reduced form.
g<- function(x){
integrand<-function(y) {exp(-x^2)*y}
g<-integrate(integrand,0,1)
}
h<-function(x) log((g(x)))
g is an object of the class function, but g(2) is a integrate object,
I can print(g(2)) an get a result, but
if I try h(2) R says is a nonnumeric argument for a mathematical
function. My goal is to maximize h.
what´s wrong?
thanks
