Dear UseRs,
I declared a `$` method for a S4 class. Can I have ab automatic
completion
for this operator in R? Lists and environment objects provide this
feature
by default, but my object is an extension of "function" class which does
not
have subseting defined. How to be?
Completion should be automatic if you define names() to return the valid
names.

Hi,
Shouldn't this be delegated to a custom method. ie :
complete<- function( x, ... ){
UseMethod( "complete" )
}
complete.default<- function( x, ... ){
names( x )
}
or maybe the equivalent S4 incantation.
This would separate the completion from the names, and therefore give more
flexibility to class writers.
Ideally yes (although "complete" doesn't seem the best choice; this is
only for $ completion). It's an easy enough change, and I'll be happy
to make it if there's interest (and a use case where names() has good
reason to be different).

The motivation for this was for java object references in rJava (jobjRef
class). See this: http://tr.im/vQkf
