Gets the cell indices unit by unit

Description

Gets the cell indices unit by unit of all or a subset of the units.

Usage

## S3 method for class 'AffymetrixCdfFile'
getCellIndices(this, units=NULL, ..., useNames=TRUE, unlist=FALSE, force=FALSE,
  cache=TRUE, verbose=FALSE)

Arguments

units	The units of interest. If NULL, all units are considered.
...	Additional arguments passed to readCdfCellIndices.
useNames	If TRUE, element names are returned, otherwise not.
unlist	If TRUE, the unlisted result is returned. Using this argument is more memory efficient that calling unlist() afterwards.
force	If TRUE, cached values are ignored.
cache	If TRUE, results are cached, if not too large.
verbose	A logical or Verbose.

Details

Note, that it is much more memory efficient to do getCellIndices(cdf, useNames=FALSE, unlist=TRUE) compare with unlist(getCellIndices(cdf), use.names=FALSE).

Value

Returns the list structure returned by readCdfCellIndices.
