New generic functions for processing and analyzing microarrays.
process(object, action, parameter = NULL) analyze(object, ...)
object |
Any OOMPA class representing a microarrays or a set of microarrays |
action |
The action to process the class. |
parameter |
Any parameters needed to execute the process. |
... |
Place holder for additional parameters needed in derived classes |
In general, the analyze method represents an expensive
computational step carried out in preparation for a graphical
display, but the semantics may differ from class to class. The default
implementation of the method performs the null analysis; that is, the
return value is identical to the object that is passed in as the first
argument.
The process method represnts a function that acts on the data
of some object to process it in some way. For example, normalizing a
set of microarray data is typically one prtocessing step in a long
series that is required to take the raw data and turn it into
something useful.
Varies depending on the implementation in derived classes. Typically another object of the same or a closely related class.
