[BioC] phenodata - rtfm

[Wolfgang Huber]

Hi Hinnerk,

It is simply a dataframe with as many rows (observations) as there are
columns (chips/arrays) in the exprs matrix. You can populate it with data as
you would populate any dataframe, and use the data in models and plots just
as with any dataframe.

Hi there,

Can anyone tell me how to use the phenoData item. For one thing in a
technical sense of how to populate the object with data. And also in the
analysis sense, of how to use the data once they are there. In other
words, is it possible use those data as factors in ANOVA or plots etc?

Thanks for your help!

Best,
Hinnerk
