Sorry, I was stupid:
MyRefObj <- setRefClass("Blabla", .)
One can always get the generator object of an defined class with
'getRefClass()'. So:
g <- getRefClass("Blabla")
x <- g$new(.)

Betreff: R5 reference classes: how to initialize exactly?
Dear List,
So far, I really like those new R5 classes. But what kind of puzzles me is
that it's not just enough to define the actual reference class, I also have
to assign it to an object (e.g. 'MyRefObj') in order to fire
'MyRefObj$new(.)'.
S4:
setClass("Blabla", .)
x <- new("Blabla")
R5:
MyRefObj <- setRefClass("Blabla", .)
x <- MyRefObj$new(.)
But then how do I define a reference class in a package that should be
available after the package is loaded via 'library(my_pkg)' as there is no
'MyRefObj' at startup yet? Do I have to call the script where the definition
lives?
Thanks for any comments,
Janko
