Methods "process" and "analyze"
Description
New generic functions for processing and analyzing microarrays.
Usage
## S4 method for signature 'ANY'
process(object, action, parameter=NULL)
## S4 method for signature 'ANY'
analyze(object, ...)
Arguments
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 |
... |
extra arguments for generic routines |
Details
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 represents 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 processing step in a long series
that is required to take the raw data and turn it into something useful.
Value
The form of the value returned by either process or analyze
depends on the class of its argument. See the documentation of the particular
methods for details of what is produced by that method.
