coerce-method: Coerce a maiges object to classes defined by packages limma and marray

Description

Coercing methods were defined to convert maiges objects of classes maiges and maigesRaw into objects of classes marrayNorm and marrayRaw from package marray or classes MAList and RGList from package limma and vice-versa.

Arguments

from

object of class maiges, maigesRaw, MAList, RGList, marrayNorm or marrayRaw.

to

character string specifying the class of object to which the object from will be coerced

Methods

from = maiges, to = marrayNorm

convert an object of class maiges into an object of class marrayNorm.

from = marrayNorm, to = maiges

convert an object of class marrayNorm into an object of class maiges.

from = maiges, to = MAList

convert an object of class maiges into an object of class MAList.

from = MAList, to = maiges

convert an object of class MAList into an object of class maiges.

from = maigesRaw, to = marrayRaw

convert an object of class maigesRaw into an object of class marrayRaw.

from = marrayRaw, to = maigesRaw

convert an object of class marrayRaw into an object of class maigesRaw.

from = maigesRaw, to = RGList

convert an object of class maigesRaw into an object of class RGList.

from = RGList, to = maigesRaw

convert an object of class RGList into an object of class maigesRaw.

Details

When converting from objects of classes RGList or marrayRaw to class maigesRaw, the slot Sf and Sb will always receive the channel 2 (red) values, and Rf and Rb will always receive channel 1 (green) values. For the normalized ojects, the slot W will be equivalent to the M values.

When converting from objects of classes maigesRaw or maiges to classes RGList, marrayRaw, MAList or marrayNorm the correct values of the two channels or of M values are calculated.
