Hi all,



I am having a problem trying to declare a slot representation to hold a file connection.

With V2.8.0 I had been using:



setClass("Element",

    representation(

        [other slots removed],

        datafileConn    = setOldClass(c("file","connection"))

    )

)



This resulted in a warning but still ran okay.



No however with V2.9.0 I am getting an error:



Error in representation(state = "list", initialState = "list", polygons = "list",  :

  element 12 of the representation was not a single character string



How can I declare a slot of the appropriate class?  The strings "connection", "file" fail.
