exprSet2-class {limma} | R Documentation |
A class for storing intensity values from microarray experiments.
This class is similar to exprSet
.
This class is not yet used in the limma package but is intended to unify single-channel and log-ratio analyses of spotted microarray data in the future.
matrix
containing intensity data on log-2 scale.
For two-color arrays, odd columns will usually correspond to channel 1 (green) and even columns to channel 2 (red) for different arrays.matrix
containing non-negative quality weightsdata.frame
containing factors corresponding to the columns of expressions
data.frame
containing gene IDs or annotation information.
Should have same number of rows as expression
list
containing information about the printing processcharacter
exprSet2
objects inherit a show
method from the virtual class LargeDataObject
, which means that exprSet2
objects will print in a compact way.
