Thanks Gabor,
I solved the problem.
Here is the code in case somebody else wants to have full completions for
proto objects:

, with no default
What is going on?? My ls.proto works nicely in global env but does not
when called from attached packages?
Would really appreciate if someone can enlighten me.
Thanks a lot.
PS: I also tried to modify utils:::specialCompletions directly, did not

Hello everyone,
I am trying to implement completion for proto objects. Proto extends
environment in a hierarchical way. Thus completion should list all the
names in all it's parent environments.
For "normal" classes defining names.class would do the job, but completion

This is a BUGS error message that indeed tells you that BUGS cannot

Yes, indeed, that does not work in OpenBugs as well. Means that
documentation of Open bugs is incorrect (they are using dnorm there).
Also "I" works

You have to understand the difference between the lexical scope of a
function (which gives the search path for variables) and call stack (which
is a path of function calls). This gives an enormous flexibility in
programming, perhaps at the cost of confusing some people.
See http://cran.r-pr
Completion should be automatic if you define names() to return the valid
names.
Thank you Deepayan, that works beautifully. I wonder though; names
function for environment objects always returns NULL, but completion still
works. Looks tricky.
