EList-class: Expression List - class
Description
A list-based S4 classes for storing expression values (E-values), for example for a set of one-channel microarrays or a set of RNA-seq samples.
EListRaw holds expression values on the raw scale.
EList holds expression values on the log scale, usually after background correction and normalization.
EListRaw objects are often created by read.maimages, while
EList objects are often created by normalizeBetweenArrays or by voom.
Alternatively, an EList object can be created directly by new("EList",x), where x is a list.Methods
These classes inherit directly from class list so any operation appropriate for lists will work on objects of this class.
In addition, EList objects can be subsetted and combined.
EList objects will return dimensions and hence functions such as dim, nrow and ncol are defined.
ELists also inherit a show method from the virtual class LargeDataObject, which means that ELists will print in a compact way.See Also
02.Classes gives an overview of all the classes defined by this package.
ExpressionSet is a more formal class in the Biobase package used for the same purpose.
