I ran you script and it came back in less than 1 second:
x <- rnbinom(100, mu = 10, size = 10)
hdev <- function(par) {
+ -sum(dnbinom(x, mu = par[1], size = par[2], log = TRUE))
+ }
nlminb(c(9, 12), hdev)
$par

Hi, dear R experts ,
I am new. I met this problem when I am trying to learn how to use
the nlminb() function. I tried the example which the document
provides ( as the following code ) and R gives no response . I don't
know whether it is running or not and it takes a very long time but
still output nothing so I just close the session window. my question
is is there any method that I can see the running status of a R
program or what can I do if R gives no response??? thank you in
advance.
here is my sessionInfo

x <- rnbinom(100, mu = 10, size = 10)
hdev <- function(par) {
-sum(dnbinom(x, mu = par[1], size = par[2], log = TRUE))
}
nlminb(c(9, 12), hdev)
