[ESS] showing function syntax

[Jannis]

Dear list,


I vaguely remeber that ESS has the functionality to show the syntax of a 
R function (i.e. all the options with their defaults in the parantheses 
(e.g. for example plot(x,y,xlim,......)) in some buffer while typing the 
name of that function.

Is this correct? If yes, do I have to activate this feature? I recently 
updated emacs and ESS and no I do not have this feature anymore. And I 
am quite sure that it worked before....Or do I mistake this with rkward?


Thanks a lot
Jannis
