readCdfGroupNames {affxparser} | R Documentation |
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.
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 corrsponding unit.
