[BioC] beadarray example data problem 2

[Martin Morgan]

Hi Keith -- I'll let Mark make changes to his package, but actually a
quick peak at the documentation for assayDataNew (e.g.,
help("assayDataNew")) shows that the argument should be 'storage.mode'
rather than storageMode. 

By default, assayDataNew returns an 'environment', which is what you
see with your first example. You can see the contents of an
environment with the 'ls()' command (this is analogous to 'names()'
applied to lists), and can access individual members of the environment
with '$' or '[[' (you cannot subset an environment with '[',
though).

Probably the data is there and usable, just not in the form expected.

Hope that helps,

Martin
