[Bioc-devel] class declaration

You are not doing anything wrong (almost), but you need to have the 
definitions of ExpressionSet before you can use those: library(Biobase)

However, I do not think it is a very good idea to declare a class with a 
space in its name -- even if R allows that you never know where you are 
going to use this definition and a space is a very particular character 
in most programming languages -- it separates keywords, definitions, 
concepts etc

Best,

Dear all,

I am creating a class for my function composed by two expression set:

let say

setClass("my class",  representation(a="ExpressionSet", b="ExpressionSet")

when I lunch it I retrieve this warning.

[1] "my class"
Warning message:
In .completeClassSlots(ClassDef, where) :
  undefined slot classes in definition of "my class": a(class
"ExpressionSet"), b(class "ExpressionSet")

how can  solve this problem?
