Description Usage Arguments Value Author(s) See Also

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.

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

`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.

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.
