There is an error in your call to `optim'. The`lower' bound is incorrect:
lower=c(rep(-1,n),1e-5,1e-5,1e5)
This should be:
lower=c(rep(-1,n),1e-5,1e-5,1e-5)
I am not sure if this fixes the problem, but it is worth a try.
I do not understand your scaling. From the lower and upper bounds it se

I am using the function optim and I get the error message
ABNORMAL_TERMINATION_IN_LNSRCH. Reason for this could be a scaling problem.
Thus, I used parscale in order to scale the parameters. But I still have the
error message. For example, with parscale=c(rep(1,n), 0.01,1,0.01):
return(optim(c(
