Objects within environment

Hi all, I have following environments loaded with my current R session:
search()
[1] ".GlobalEnv" "package:stats" "package:graphics" "package:grDevices" [5] "package:utils" "package:datasets" "package:methods" "Autoloads" [9] "package:base" How can I find the objects under a specific environment? Here I tries following:
objects(envir="package:base")
Error in objects(envir = "package:base") : invalid 'envir' argument
It would be great if somebody would point me the correct arguments for object() function to find the onjects associated with it. In help file it is written that:
" envir: an alternative argument to ?name? for specifying the
environment evaluation environment. Mostly there for back
compatibility"
What is the wrong in my code?
The easiest way to pick an item from the search list is by number:
objects(3)
or
ls(3)
will give you the objects in the graphics package, with the search list
as above. You can also specify the name as the name argument, e.g.
objects("package:base")
If you want to use the envir argument (why?), you need to give an
environment, not the name of one.
