Function argument display on GUI console border

The display of function arguments along the lower border of the  
Console window now seems very erratic. If I now type

duplicated(

... I was expecting to see the usage argument list along the lower  
border. Am I the only one who has seen this feature become less  
predictably available?

You should see

duplcated(x, incomparables = FALSE, ...)

in the bottom bar - at least that's what I get.

            

      
      
      
    

        
You'll have to be more precise as of what you see .... Since the console essentially just evaluates capture.output(print(args(...))), you can obviously break it by any R code that changes the behavior of the pieces involved. But then I don't know why anyone would to that ... ;)

Cheers,
Simon

The display of parameters seems to be reproducibly inhibited after  
backspacing  or selecting and deleting a function name that had an  
argument list displayed. If I type "duplicated(", and then see an  
argument list , then backspace over it and hit <enter> and then type  
"duplicated(" again,  I see no arguments. I did discover by accident  
that I sometimes get back the desired behavior after typing  
sessionInfo(). I will generally get display of arguments from other  
functions after that, but "duplicated" seems to be blanked out until  
<something happens to make it recognized again>.

Ah, yes - I see there is a check whether that function was already displayed which inhibits the repeated display (added in r5773 - I'm not sure why, possibly optimization to prevent re-fetching the argument list). Now fixed.

Thanks,
Simon
