[BioC] Does old workspace work?

With the show(obj) function and the write.table function, I can see the
stuff in the old objects so that may solve the immediate problem
But changing exprSet to ExpressionSet is attractive
And I see it has been discussed before (see below)
===========================
[BioC] Error loading, on Bioconductor 1.8, exprSet generated with
bioconductor 1.7

Hi Raf,
Thanks for the clarification. It sounds like you've found a good
solution.
The long-term intention is to move away from exprSet as the basic
building block, and toward a similar 'ExpressionSet' class. With this
in mind, you could also have done (with the current version of
Biobase)
> obj <- as(tr7.rma, "ExpressionSet")
to obtain an ExpressionSet from your (broken) exprSet. An
ExpressionSet has methods like exprs(), phenoData(), and pData() that
work as exprSet methods, so for many purposes having an ExpressionSet
is a great replacement for exprSet.
It's important to be able to return to previous versions of objects,
and make them 'current'. To that end, the development version of
Biobase introduces ways of 'versioning' objects (so that it's easy to
figure out when the object was created) and an 'updateObject' method
to bring an object up to date. So in the next release of Biobase
(available to those already using the 'development' branch of R)
you'll be able to
> obj <- updateObject(tr76.rma)
and stand a reasonable chance of getting an object that satisfies the
current definition of exprSet.
=============================================
So I try
> ABeset_gcrmaExpressionSet <- as (ABeset_gcrma, "ExpressionSet")
And get
Loading required package: Biobase
Loading required package: tools

Warning message:
In asMethod(object) :
missing or mis-shaped 'se.exprs' in original object; creating
ExpressionSet without se.exprs
Then I try
> ABeset_gcrmaUPDATE <- updateObject(ABeset_gcrma)
And get
Error in updateObjectFromSlots(object, ..., verbose = verbose) :
could not updateObject to class 'phenoData'

Now since I can "see" the data with show and write.table I should probably
quit, but for the fun of it, are either of these messages a "quick fix" for
a novice?
