getCellIndices.AffymetrixCdfFile: 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 AffymetrixCdfFile
getCellIndices(this, units=NULL, ..., useNames=TRUE, unlist=FALSE, force=FALSE,
  cache=TRUE, verbose=FALSE)

Value

Returns the list structure returned by

readCdfCellIndices.

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).
