read.affy: Read a Set of .CEL Files and Phenotypic Data

In simpleaffy: Very simple high level analysis of Affymetrix data

Description

Reads the specified file, which defines phenotypic data for a set of .CEL files. Reads the specified files into an AffyBatch object and then creates a phenoData object, defining the experimental factors for those chips.

Usage

read.affy(covdesc = "covdesc",path=".", ...)

Arguments

covdesc	A white space delimited file suitable for reading as a data.frame. The first column (with no column name) contains the names(or paths to) the .CEL files to read. Remaining columns (with names) represent experimental factors for each chip. these become elements of the phenoData object.
...	extra functions to pass on to ReadAffy
path	The path to prefix the filenames with before calling ReadAffy

Value

An AffyBatch object
