I agree with Wolfgang. I am currently working on environments that are
not completely unrelated to the one provided by the Data package and
I would like to attach extra information to the environment.
I would be happy to follow a convention to stick the information to the
environment.
Here are few thoughts about that (just in case):
- set a class for 'Data' environment (chipData)
- set an attribute 'cdfName' (to be used with the affy package.
  indicates the chip it corresponds to)
- set an attribute 'releaseDate' or 'bestBefore'
- set an attribute 'size' (memory usage)
- set an attribute 'comments'





Cheers,




L.
