Thanks, that always gets me for some reason. Now when I run it though I
get an error message at the very end that states "could not find function
"M.n". I don't understand why I'm getting this message b/c there is no
where that calls a function named "M.n" and I don't define a function with
that n

The argument is minuslogl
Note: l instead of 1

Hello,
I've recently run into a problem when trying to do some MLE parameter
estimation in R using a non-linear Kalman filter. I've written some of the
functions myself and everything seems to be working fine until the end when
I try to use the mle2 function written for R. The error message stat
sorry I solved it, was a typo on my part!!

Hi there,
I am trying to run the following code:
> dcOU<-function(x,t,x0,theta,log=FALSE){
+ Ex<-theta[1]/theta[2]+(x0-theta[1]/theta[2])*exp(-theta[2]*t)
+ Vx<-theta[3]^2*(1-exp(-2*theta[2]*t))/(2*theta[2])
+ dnorm(x,mean=Ex,sd=sqrt(Vx),log=log)
+ }
> OU.lik<-function(theta1,theta2,theta3){
+ n<
