[Bioc-devel] class declaration

[Oleg Sklyar]

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
