Usage

AffymetrixCelFile(..., cdf=NULL)

Arguments

...
Arguments passed to AromaMicroarrayDataFile.
cdf
An optional AffymetrixCdfFile making it possible to override the default CDF file as specified by the CEL file header. The requirement is that its number of cells must match that of

Fields and Methods

Methods: rll{ [ - [[ - clone - extractMatrix - fromFile Defines an AffymetrixCelFile object from a CEL file. getAm - getCdf Gets the CDF structure for this CEL file. getFileFormat - getImage Creates an RGB Image object from a CEL file. getUnitNamesFile - getUnitTypesFile - highlight - image270 Displays all or a subset of the data spatially. nbrOfCells - plotDensity Plots the density of the probe signals on the array. plotImage Displays a spatial plot of a CEL file. plotMvsA Plots log-ratio versus log-intensity in a scatter plot. plotMvsX Plots log-ratio versus another variable in a scatter plot. setCdf Sets the CDF structure for this CEL file. smoothScatterMvsA Plots log-ratio versus log-intensity in a smooth scatter plot. writeImage Writes a spatial image of the signals in the CEL file. } Methods inherited from AromaPlatformInterface: getAromaPlatform, getAromaUgpFile, getPlatform, getUnitAnnotationDataFile, getUnitNamesFile, getUnitTypesFile, isCompatibleWith Methods inherited from AromaMicroarrayDataFile: getAttributeXY, getChipType, getPlatform, getPloidy, getXAM, hasAttributeXY, isAverageFile, setAttributesByTags, setAttributeXY Methods inherited from GenericDataFile: getParentName, compareChecksum, copyTo, equals, fromFile, getAlias, getAttribute, getAttributes, getChecksum, getCreatedOn, getDefaultFullName, getExtension, getExtensionPattern, getFilename, getFilenameExtension, getFileSize, getFileType, getLastAccessedOn, getLastModifiedOn, getOutputExtension, getPath, getPathname, gunzip, gzip, hasBeenModified, isFile, readChecksum, renameTo, renameToUpperCaseExt, setAlias, setAttribute, setAttributes, setAttributesBy, setAttributesByTags, setExtensionPattern, testAttributes, validateChecksum, writeChecksum Methods inherited from FullNameInterface: appendFullNameTranslator, appendFullNameTranslatorBycharacter, appendFullNameTranslatorBydata.frame, appendFullNameTranslatorByfunction, appendFullNameTranslatorBylist, appendFullNameTranslatorByNULL, appendFullNameTranslatorByTabularTextFile, appendFullNameTranslatorByTabularTextFileSet, clearFullNameTranslator, clearListOfFullNameTranslators, getDefaultFullName, getFullName, getFullNameTranslator, getListOfFullNameTranslators, getName, getTags, hasTag, hasTags, setFullName, setFullNameTranslator, setListOfFullNameTranslators, setName, setTags, updateFullName Methods inherited from Object: asThis, getChecksum, $, $<-, [[, [[<-, as.character, attach, attachLocally, clearCache, clearLookupCache, clone, detach, equals, extend, finalize, gc, getEnvironment, getFieldModifier, getFieldModifiers, getFields, getInstantiationTime, getStaticInstance, hasField, hashCode, ll, load, objectSize, print, registerFinalizer, save

For developers

If you subclass this class, please make sure to query the AffymetrixCdfFile object (see *getCdf()) whenever querying CDF information. Do not use the CDF file inferred from the chip type in CEL header, unless you really want it to be hardwired that way, otherwise you will break to possibility to override the CDF structure.
