y - c(5, 2, 4, 3, 1)
y
[1] 5 2 4 3 1
and suppose that I want to find where 3 occurs in y. Then, the following
yields the
You're not too far off.
You need to do something like
objfun - function(p) {
mu - p[1]
sigma - p[2]
-sum(dnorm(x,mean=mu,sd=sigma,log=TRUE))
}
optim(par=c(0,1),fn=objfun) # check ?optim for correct argument names
Some points:
- the main thing is that you have to define mu and
