Reads group names for a set of units (probesets) in an Affymetrix CDF file

Description

Reads group names for a set of units (probesets) in an Affymetrix CDF file.

This is for instance useful for SNP arrays where the nucleotides used for the A and B alleles are the same as the group names.

Usage

readCdfGroupNames(filename, units=NULL, truncateGroupNames=TRUE, verbose=0)

Arguments

filename

The filename of the CDF file.

units

An integer vector of unit indices specifying which units to be read. If NULL, all units are read.

truncateGroupNames

A logical variable indicating whether unit names should be stripped from the beginning of group names.

verbose

An integer specifying the verbose level. If 0, the file is parsed quietly. The higher numbers, the more details.

Value

A named list structure where the names of the elements are the names of the units read. Each element is a character vector with group names for the corresponding unit.
