I want to use the nlminb function but I have the objective function like
characters. I can summarize the problem using the first example in the
x <- rnbinom(100, mu = 10, size = 10)
hdev <- function(par) -sum(dnbinom(x, mu = par, size = par, log =
nlminb(c(9, 12), objective=hdev)
With the last instructions we obtain appropriate results. If I have the name
of the objective function stored in the element name, how can modify the
next two instructions to obtain the same above results?
name <- 'hdev'
nlminb(c(9, 12), objective=name)
Thanks for the reply.
