clearData,AffymetrixCelFile-method

A <code><a href="/link/character?package=aroma.affymetrix&version=1.6.0&to=base" rd-options="base" data-mini-rdoc="base::character">character</a></code> <code><a href="/link/vector?package=aroma.affymetrix&version=1.6.0&to=base" rd-options="base" data-mini-rdoc="base::vector">vector</a></code> of fields to be cleared.

fields

A <code><a href="/link/numeric?package=aroma.affymetrix&version=1.6.0&to=base" rd-options="base" data-mini-rdoc="base::numeric">numeric</a></code> value to be written over the data.

value

Additional arguments passed to the
     <code><a href="/link/updateCelUnits?package=aroma.affymetrix&version=1.6.0&to=affxparser" rd-options="affxparser" data-mini-rdoc="affxparser::updateCelUnits">updateCelUnits</a></code> methods.

If not <code><a href="/link/TRUE?package=aroma.affymetrix&version=1.6.0&to=base%3Alogical" rd-options="base:logical" data-mini-rdoc="base:logical::TRUE">TRUE</a></code>, an exception is thrown asking if the
     method was called by mistake.

.forSure

A <code><a href="/link/logical?package=aroma.affymetrix&version=1.6.0&to=base" rd-options="base" data-mini-rdoc="base::logical">logical</a></code> or <code><a href="/link/Verbose?package=aroma.affymetrix&version=1.6.0&to=R.utils" rd-options="R.utils" data-mini-rdoc="R.utils::Verbose">Verbose</a></code>.

verbose

Clears all or a subset of the fields in a CEL file.

internal

This package implements classes for files and sets of
        files for various Affymetrix file formats, e.g.
        AffymetrixCdfFile, AffymetrixCelFile, and AffymetrixCelSet.
        These are designed to be memory efficient but still being fast.
        The idea is to keep all data on file and only read data into
        memory when needed.  Clever caching mechanisms are used to
        minimize the overhead of data IO.  All of the above is hidden
        in the package API and for the developer (and the end user),
        the data is queried as if it lives in memory.  With this design
        it is only the diskspace that limits the number of arrays that
        can be analyzed.
