how to directly open the doc page of a s4 class?

Question

Is there a way to directly open the doc page of a s4 class? for example the mle-class:

http://127.0.0.1:16875/library/stats4/html/mle.html

I have tried the followings, none seem to work:

?mle-class
?`mle-class`
?"mle-class"

Answer 1

You must load the package first. This does work:

library(stats4)
?"mle-class"

as does these, also assuming you have done it after loading the package:

?`mle-class`

class?mle
