Hi Andre,
1. Keep in mind that a S4 method belongs to a specific generic function,
not to a specific object or class. There is none such thing as a class
member function in the S4 system. As an example for illustration,
consider the following class definitions in Java:
class myClassA
{

Dear all,
I do not completely understand following behaviour :
con - file(test.txt)
isOpen(con)
[1] FALSE
open(con)
isOpen(con)
[1] TRUE
close(con)
isOpen(con)
Error in isOpen(con) : invalid connection
str(con)
Classes 'file', 'connection' atomic [1:1] 3

I need a function which is similar to duplicated(), but instead of
returning TRUE/FALSE, returns indices of which element was duplicated.
That is,
x - c(9,7,9,3,7)
duplicated(x)
[1] FALSE FALSE TRUE FALSE TRUE
duplicates(x)
[1] NA NA 1 NA 2
(so that I know that element 3 is a
How about:
y - rep(NA,length(x))
y[duplicated(x)] - match(x[duplicated(x)] ,x)

Thx for the information. I read it, but I wasn't sure what was going
on inside. Is there a way to close a connection without destroying it?
Guess not, but you never know...

I use Joshua's trick all the time. But it might still be nice with a
C implementation.
While we are discussing duplication, I would
Thank you very much, gentlemen. It seems reference classes will make my life
much easier. I won't pretend that i fully understand the wizardry with
environments that you do, but it works :). Namely the steps to mtrace a
class method by doing what John and Mark outlined
