Hello,

I'm trying to make .DollarNames generic and implement a method for it in a package. .DollarNames is the function that is now called to get completion possibilities.

My R code looks like this:

setGeneric( ".DollarNames" )

setClass("track",
         representation(x="numeric", y="numeric"))
## A class extending the previous, adding one more slot
setClass("trackCurve",
    representation(smooth = "numeric"),
    contains = "track")

setMethod( ".DollarNames", signature( x = "track", pattern = "character" ), function(x, pattern){
        grep( pattern, c("foo", "bar"), value = TRUE )      
} )


and the NAMESPACE :

import( utils )
exportMethods( .DollarNames )
exportClasses( track, trackCurve )


When I load the package, I can call .DollarNames explicitely :

> require( foo )
> x <- new( "trackCurve", x = 1:10, y = 1:10, smooth = 1:10 )
> .DollarNames( x, "f" )
[1] "foo"

but completion does not work :

> x$f<TAB>
x$


What do I miss ?

I've uploaded foo here : http://addictedtor.free.fr/misc/rcpp/foo_1.0.tar.gz
