Description

A class created for meta-analysis of microarray

Objects from the Class

Objects can be created by calls of the form new("MetaArray", ...).

Slots

GEDM:

Object of class "list" - gene expression data matrices are stored in individual slot of the list. Each matrix refer to one dataset, genes are represented in rows, samples in columns.

clinical:

Object of class "list" - clinical data matrices, clinical description of samples, rows refer to samples, columns to clinical characteristics

datanames:

Object of class "character" - vector of names of the datasets

Methods

plot

signature(x = "MetaArray", y = "missing"): draws distribution of clinical variables of several datasets. Boxplot is drawn for numerical variables and barplot for categorical ones.

print

signature(x = "MetaArray"): prints the number of samples and genes in each dataset, followed by summarization of each clinical characteristic of the samples

show

Same as print

as.list

Function transforms a MetaArray object into a list, in which each slot is again a list of three slots: gene expression data matrix GEDM, clinical data clinical, name of the dataset dataname
